This section outlines the space and resource requirements for GC, GC/MS,
and automatic liquid sampler (ALS) installation. For a successful and
timely installation of the instrument, the site must meet these
requirements before beginning installation. Necessary supplies (gases,
tubing, operating supplies, consumables, and other usage- dependent items
such as columns, vials, syringes, and solvents) must also be available. Note
that performance verification requires the use of helium carrier gas. For
MS systems using chemical ionization, methane reagent gas or methanol
(for internal ionization ion traps) is also required for performance
verification. Refer to the Agilent Web site at www.agilent.com/chem for the
most up- to- date listing of GC, GC/MS, and ALS supplies and consumables.
For 7697A Headspace Sampler site prep specifications, refer to the 7697A
Site Prep Guide.

Customer Responsibilities
The specifications in this manual outline the necessary space, electrical
outlets, gases, tubing, operating supplies, consumables, and other
usage- dependent items such as columns, vials, syringes, and solvents
required for the successful installation of instruments and systems.
If Agilent is delivering installation and familiarization services, users of
the instrument should be present throughout these services; otherwise,
they will miss important operational, maintenance, and safety information.
If Agilent is delivering installation and familiarization services, delays due
to inadequate site preparation could cause loss of instrument use during
the warranty period. In extreme cases, Agilent Technologies may ask to be
reimbursed for the additional time required to complete the installation.
Agilent Technologies provides service during the warranty period and
under maintenance agreements only if the specified site requirements are
met.

Hydrogen Carrier Gas
If planning to use hydrogen carrier gas, note that special considerations
apply due to hydrogen’s flammability and chromatographic properties.
• Agilent highly recommends the G3388B Leak Detector to safely check
for leaks.
• Hydrogen carrier gas requires special considerations for supply tubing.
See “Gas Plumbing” on page 43.
• In addition to the supply pressure requirements listed in “Gas
Supplies” on page 35, Agilent also recommends users of hydrogen
carrier gas consider the gas source and purification needs. See the
additional recommendations in “Requirements for hydrogen as a carrier
gas” on page 37.

Dimensions and Weight
Select the laboratory bench space before the system arrives. Make sure the
area is clean, clear, and level. Pay special attention to the total height
requirements. Avoid bench space with overhanging shelves. See Table 2.
The instrument needs space for proper convection of heat and ventilation.
Allow at least 25 cm (10 in) clearance between back of the instrument
and wall to dissipate hot air and allow for routine maintenance.

A system that includes a 7890 Series GC, a 5977, 5975 or 7000 MS, an
ALS, and a computer would require about 168 cm (5.5 ft) of bench space
(see Figure 1). A 7890 Series system with a GC, Ion Trap MS, ALS, and
computer would require about 206 cm (6.7 ft) of bench space (or 148 cm
[4.8 ft] excluding the area under the tray.) See Figure 2. Allowing for
operational access and a printer, a total of 260 cm (8.5 ft) of bench space
should be available for a quadrupole GC/MS system and 298 cm (9.7 ft)
should be available for an Ion Trap GC/MS system. Some repairs to the
GC/MS or to the GC will also require access to the back of the
instrument(s).

GC, GC/MS, and ALS Site Preparation Guide
7890 Series GC Site Preparation
CAUTION
The supporting surface for the 7200 Q-TOF GC/MS system should be kept relatively
vibration free. Do not put the rough pump on your laboratory bench with the 7200
Q-TOF GC/MS due to the vibration that the pump creates. Vibration can lead to a loss
of mass accuracy and resolution.
CAUTION
Make sure the 7200 Q-TOF GC/MS foreline pump is located where it is not likely to be
touched by operators.
If using an ion trap MS:
The vacuum hose connecting the Ion Trap MS to the foreline pump is
200 cm (79 in) long. To accommodate the pump vacuum hose, the
bench should be no higher than 91 cm (3 ft). If your bench is higher,
place a bench that can support a 22 kg (48 lb) pump and isolate
vibration under the bench. If your bench abuts a wall, drill a 3.8 cm
(1.5 in) diameter hole through the rear of the bench for the vacuum
hose.
A 7890 Series GC shipping pallet for a GC is approximately 76 cm ×
86 cm × 10 cm (30 × 34 × 40.5 inches). For a 7890 Series GC with a thrid
detector, the pallet size is approximately 76 cm × 87 cm × 11 cm (30 × 34
× 42.5 inches).

* Option 003, 208 VAC fast oven, uses a 220 VAC unit with operating range of 198 to 242 VAC. Most labs have 4-wire service
resulting in 208 VAC at the wall receptacle. It is important to measure the line voltage at the receptacle for the GC.

Do not use extension cords with Agilent instruments. Extension cords normally are
not rated to carry enough power and can be a safety hazard.
Although your GC should arrive ready for operation in your country,
compare its voltage requirements with those listed in Table 3. If the
voltage option you ordered is not suitable for your installation, contact
Agilent Technologies. Note that ALS instruments receive their power from
the GC.
CAUTION
A proper earth ground is required for GC operations. Any interruption of the grounding
conductor or disconnection of the power cord could cause a shock that could result in
personal injury.
To protect users, the metal instrument panels and cabinet are grounded
through the three- conductor power line cord in accordance with
International Electrotechnical Commission (IEC) requirements.
The three- conductor power line cord, when plugged into a properly
grounded receptacle, grounds the instrument and minimizes shock hazard.
A properly grounded receptacle is one that is connected to a suitable
earth ground. Be sure to verify proper receptacle grounding. The GC
requires an isolated ground.
Connect the GC to a dedicated circuit.

USA fast heating oven, 240 V
The 240 V fast heating oven requires 240 V/15 A power. Do not use 208 V
power. Lower voltage causes slow oven ramps and prevents proper
temperature control. The power cord supplied with your GC is rated for
250 V/15 A, and is a two- pole, three- wire cord with grounding (type
L6- 15R/L6- 15P).
Canadian installation
When installing a GC in Canada, make sure your GC’s power supply
circuit meets the following additional requirements:
• The circuit breaker for the branch circuit, which is dedicated to the
instrument, is rated for continuous operation.
• The service box branch circuit is marked as a “Dedicated Circuit.”

Exhaust Venting
Hot air (up to 450 °C) from the oven exits through a vent in the rear.
Allow at least 25 cm (10 in) clearance behind the instrument, or 30 cm
(12 in) behind a Q- TOF GC/MS, and 76 cm (30 in) above the Ion Trap to
dissipate this air.
WA R N I N G
Do not place temperature-sensitive items (for example, gas cylinders, chemicals,
regulators, and plastic tubing) in the path of the heated exhaust. These items will be
damaged and plastic tubing will melt. Be careful when working behind the
instrument during cool-down cycles to avoid burns from the hot exhaust.
For most applications, an optional oven exhaust deflector (G1530- 80650,
or option 306) is available and can improve oven cooling by deflecting the
exhaust air up and away from the instrument. The exhaust deflector
requires 14 cm (5.5 inches) behind the instrument. (For 7200 Q- TOF
GC/MS, GC/QTOF exhaust deflector assembly G3850- 80650 is provided.)
For GCs with the exhaust deflector option installed, the exhaust is about
65 ft3/min (1.840 m3/min). Without the deflector, the exhaust rate is
about 99 ft3/min (2.8 m3/min). The deflector outlet diameter is 10 cm
(4 in).

Exhaust deflector G1530-80650
During normal operation of the GC with many detectors and inlets, some
of the carrier gas and sample vents outside the instrument through the
split vent, septum purge vent, and detector exhaust. If any sample
components are toxic or noxious, or if hydrogen is used as the carrier gas,
these exhausts must be vented to a fume hood. Place the GC in the hood
or attach a large diameter venting tube to the outlet for proper ventilation.
To further prevent contamination from noxious gases, attach a chemical
trap to the vent(s).
Vent the GC/MS system externally to the building via an ambient- pressure
vent system, within 460 cm (15 ft) of both the GC split vent and GC/MS
foreline pump, or vent to a fume hood.
Note that an exhaust vent system is not part of the building
environmental control system, which recirculates air.
Exhaust venting must comply with all local environmental and safety
codes. Contact your Environmental Health & Safety (EHS) specialist.

Gas and Reagent Selection
Table 7 lists gases usable with Agilent GCs and capillary columns. When
used with capillary columns, GC detectors require a separate makeup gas
for optimum sensitivity. The MS and MSD use GC carrier gas.
If using any MS system, use of hydrogen as the carrier gas may require
hardware modifications for best performance. Contact your Agilent service
representative. Hydrogen is not supported as a carrier gas with the 7200
GC/QTOF system.

When using hydrogen (H2) as the carrier gas or fuel gas, be aware that hydrogen
gas can flow into the GC oven and create an explosion hazard. Therefore, be sure
that the supply is turned off until all connections are made and ensure the inlet and
detector column fittings are either connected to a column or capped at all times
when hydrogen gas is supplied to the instrument.
Hydrogen is flammable. Leaks, when confined in an enclosed space, may create a
fire or explosion hazard. In any application using hydrogen, leak test all
connections, lines, and valves before operating the instrument. Always turn off the
hydrogen supply at its source before working on the instrument.
Please refer to the Hydrogen Safety Guide shipped with your instrument.
Hydrogen use is specifically prohibited with the 7200 GC/Q-TOF system.

Requirements for hydrogen as a carrier gas
Not all systems can use hydrogen as a carrier gas. See Gas and Reagent
Selection.
Hydrogen can be supplied from a generator or from a cylinder.
Agilent recommends use of a high- quality hydrogen gas generator. A
high- quality generator can consistently produce purity > 99.9999%, and the
generator can include built- in safety features such as limited storage,
limited flow rates, and auto- shutdown. Select a hydrogen generator that
provides low (good) specifications for water and oxygen content.
If using a hydrogen gas cylinder, Agilent recommends use of Gas Clean
Filters to purify the gas. Consider additional safety equipment as
recommended by your company safety personnel.

All compressed gas cylinders should be securely fastened to an immovable
structure or permanent wall. Compressed gases should be stored and handled in
accordance with the relevant safety codes.

• If you have not requested option 305 (pre- plumbed tubing), you must
supply pre- cleaned, 1/8- inch copper tubing and a variety of 1/8- inch
Swagelok fittings to connect the GC to inlet and detector gas supplies.
See the Installation Kits for recommended parts.
• Agilent strongly recommends two- stage regulators to eliminate pressure
surges. High- quality, stainless- steel diaphragm- type regulators are
especially recommended.
• On/off valves mounted on the outlet fitting of the two- stage regulator
are not essential but are very useful. Be sure the valves have
stainless- steel, packless diaphragms.
• Agilent strongly recommends installation of shut- off valves at each GC
inlet supply fitting to allow the GC to be isolated for maintenance and
troubleshooting. Order part number 0100- 2144. (Note that some
optional installation kits include one shut- off valve. See Installation
Kits.)
• If you purchased automated valving, the valve actuation requires a
separate pressurized, dry air supply at 380 kPa (55 psig). This air
supply must end in a male fitting compatible with a 1/4- inch id plastic
tube at the GC.
• FID, FPD, and NPD detectors require a dedicated air supply. Operation
may be affected by pressure pulses in air lines shared with other
devices.
• Flow- and pressure- controlling devices require at least
10 psi (138 kPa) pressure differential across them to operate properly.
Set source pressures and capacities high enough to ensure this.
• Situate auxiliary pressure regulators close to the GC inlet fittings. This
ensures that the supply pressure is measured at the instrument (rather
than at the source); pressure at the source may be different if the gas
supply lines are long or narrow.
• Never use liquid thread sealer to connect fittings.
• Never use chlorinated solvents to clean tubing or fittings.
See Installation Kits for more information.

GC, GC/MS, and ALS Site Preparation Guide
7890 Series GC Site Preparation
Supply tubing for most carrier and detector gases
Use only preconditioned copper tubing (part number 5180- 4196) to supply
gases to the instrument. Do not use ordinary copper tubing—it contains
oils and contaminants.
CAUTION
Do not use methylene chloride or other halogenated solvent to clean tubing that will be
used with an electron capture detector. They will cause elevated baselines and
detector noise until they are completely flushed out of the system.
CAUTION
Do not use plastic tubing for suppling detector and inlet gases to the GC. It is
permeable to oxygen and other contaminants that can damage columns and detectors.
Plastic tubing can melt if near hot exhaust or components.
The tubing diameter depends on the distance between the supply gas and
the GC and the total flow rate for the particular gas. Tubing of 1/8- in
diameter is adequate when the supply line is less than 15 feet (4.6 m)
long.
Use larger diameter tubing (1/4- in) for distances greater then 15 feet
(4.6 m) or when multiple instruments are connected to the same source.
Use larger diameter tubing if high demand is anticipated (for example, air
for an FID).
Be generous when cutting tubing for local supply lines—a coil of flexible
tubing between the supply and the instrument lets you move the GC
without moving the gas supply. Take this extra length into account when
choosing the tubing diameter.
Supply tubing for hydrogen gas
Agilent recommends using new chromatographic quality stainless steel
tubing and fittings when using hydrogen.
GC, GC/MS, and ALS Site Preparation Guide
45
7890 Series GC Site Preparation
• Do not re- use old tubing when installing or switching to hydrogen
carrier gas. Hydrogen gas tends to remove contaminants left on old
tubing by previous gases (by helium, for example). These contaminants
can appear in output as high background noise or hydrocarbon
contamination for several weeks.
• Especially do not use old copper tubing, which can become brittle.
WA R N I N G
Do not use old copper tubing with hydrogen gas. Old copper tubing can become
brittle and create a safety hazard.
Two-stage pressure regulators
To eliminate pressure surges, use a two- stage regulator with each gas
tank. Stainless steel, diaphragm- type regulators are recommended.

GC, GC/MS, and ALS Site Preparation Guide
7890 Series GC Site Preparation
The type of regulator you use depends on the gas type and supplier. The
Agilent catalog for consumables and supplies contains information to help
you identify the correct regulator, as determined by the Compressed Gas
Association (CGA). Agilent Technologies offers pressure- regulator kits that
contain all the materials needed to install regulators properly.
Pressure regulator-gas supply tubing connections
Use PTFE tape to seal the pipe- thread connection between the pressure
regulator outlet and the fitting to which you connect the gas tubing.
Instrument grade PTFE tape (part number 0460- 1266), from which
volatiles have been removed, is recommended for all fittings. Do not use
pipe dope to seal the threads; it contains volatile materials that will
contaminate the tubing.
Pressure regulators typically end in fittings that must be adapted to the
correct style or size. Table 23 lists parts needed to adapt a standard
1/4- inch male NPT fitting to a 1/8- inch or 1/4- inch Swagelok fitting.

Filters and traps
Using chromatographic- grade gases ensures that the gas in your system is
pure. However, for optimum sensitivity, install high- quality filters or traps
to remove traces of water or other contaminants. After installing a filter,
check the gas supply lines for leaks.
Agilent recommends the Gas Clean Filter system. The Gas Clean Filter
system delivers high purity gases to your analytical instruments, reducing
the risk of column damage, sensitivity loss, and instrument downtime. The
GC, GC/MS, and ALS Site Preparation Guide
47
7890 Series GC Site Preparation
filters are designed for use with the GC, GC/MS, ICP- OES, ICP- MS,
LC/MS, and any other analysis instrument using carrier gas. Six filters are
available, including CO2, oxygen, moisture, and organics trap (charcoal).
Filter types
Each Gas Clean Filter type is designed to filter out a specific impurity
that may exist in the gas supply. The following filter types are available:
• Oxygen - Prevents oxidation of the GC column, septum, liner, and glass
wool.
• Moisture - Delivers fast stabilization times for increased GC
productivity, and prevents hydrolization damage to the stationary phase,
column, liner, glass wool, or septum in the GC.
• Process Moisture - Prevents oxidation of GC components and is safe to
use with acetylene in process GC applications.
• Charcoal - Removes organic compounds and ensures correct
performance of FID detectors in the GC.
• GC/MS - Delivers fast stabilization times for increased GC productivity,
removes oxygen, moisture, and hydrocarbons from the carrier gas for
MS applications, and provides ultimate GC column protection.
Table 24 on page 49 shows recommended filter connection diagrams for
common instrument configurations.

Cryogenic Cooling Requirements
Cryogenic cooling allows you to cool the oven or inlet, including cooling to
setpoints below ambient temperature. A solenoid valve controls the flow of
coolant to the inlet or oven. The oven can use either liquid carbon dioxide
(CO2) or liquid nitrogen (N2) as a coolant. All inlets except the multimode
inlet must use the same coolant type as the oven. The multimode inlet can
use a different coolant than configured for the oven, and can also use
compressed air as a coolant.
CO2 and N2 coolants require different hardware on the GC. (You can use
air cooling on a multimode inlet, with either the CO2 or N2 solenoid
valves and hardware.)
Oven cryogenic cooling is not compatible with the 7000 Triple Quad MS or
7200 Q- TOF MS. If your application requires GC oven cryogenic cooling,
contact your Agilent sales representative.
Using carbon dioxide
WA R N I N G
Pressurized liquid CO2 is a hazardous material. Take precautions to protect
personnel from high pressures and low temperatures. CO2 in high concentrations is
toxic to humans; take precautions to prevent hazardous concentrations. Consult
your local supplier for recommended safety precautions and delivery system design.
CAUTION
Liquid CO2 should not be used as a coolant for oven temperatures below –40 °C
because the expanding liquid may form solid CO2—dry ice—in the GC oven. If dry ice
builds up in the oven, it can seriously damage the GC.
Liquid CO2 is available in high- pressure tanks containing liquid. The CO2
should be free of particulate material, oil, and other contaminants. These
contaminants could clog the expansion orifice or affect the proper
operation of the GC.
52
GC, GC/MS, and ALS Site Preparation Guide
7890 Series GC Site Preparation
WA R N I N G
Do not use copper tubing or thin-wall stainless steel tubing with liquid CO2. Both
harden at stress points and may explode.
Additional requirements for the liquid CO2 system include:
• The tank must have an internal dip tube or eductor tube to deliver
liquid CO2 instead of gas (see the figure below).
• Typical liquid CO2 tank pressure will be 4830 to 6900 kPa (700 to
1,000 psi) at a temperature of 25 °C.
• Use 1/8- inch diameter heavy- wall stainless steel tubing for supply
tubing. The tubing should be between 1.5 and 15 m (5 and 50 feet)
long. (Agilent part number 7157- 0210, 20 ft)
• Coil and fasten the ends of the tubing to prevent it from “whipping” if
it breaks.
• Do not install a pressure regulator on the CO2 tank, as vaporization
and cooling would occur in the regulator instead of the oven.
• Do not use a padded tank (one to which another gas is added to
increase the pressure).

GC, GC/MS, and ALS Site Preparation Guide
Incorrect configuration

7890 Series GC Site Preparation
Using liquid nitrogen
WA R N I N G
Liquid nitrogen is a hazard because of the extremely low temperatures and high
pressures that may occur in improperly designed supply systems.
Liquid nitrogen can present an asphyxiant hazard if vaporizing nitrogen displaces
oxygen in the air. Consult local suppliers for safety precautions and design
information.
Liquid nitrogen is supplied in insulated Dewar tanks. The correct type for
cooling purposes is a low- pressure Dewar equipped with a dip tube—to
deliver liquid rather than gas—and a safety relief valve to prevent pressure
build- up. The relief valve is set by the supplier at 138 to 172 kPa (20 to
25 psi).
WA R N I N G
If liquid nitrogen is trapped between a closed tank valve and the cryo valve on the
GC, tremendous pressure will develop and may cause an explosion. For this reason,
keep the delivery valve on the tank open so that the entire system is protected by the
pressure relief valve.
To move or replace a tank, close the delivery valve and carefully disconnect the line
at either end to let residual nitrogen escape.
Additional requirements for the liquid N2 system include:
• Cryogenic cooling with Liquid N2 requires 1/4- inch insulated copper
tubing.
• If needed, set the liquid N2 pressure to the GC at 138 to 207 kPa (20 to
30 psi). Follow the manufacturer's directions.
• Make sure the supply tubing for liquid N2 is insulated. Foam tubing
used for refrigeration and air- conditioning lines is suitable for
insulation. (Foam tubing insulation is not supplied by Agilent. Contact a
local supplier.) Since pressures are low, insulated copper tubing is
adequate.
• Situate the liquid nitrogen tank close (within 1.5 to 3 m, or 5 to
10 feet) to the GC to ensure that liquid, not gas, is supplied to the
inlet.
54
GC, GC/MS, and ALS Site Preparation Guide
7890 Series GC Site Preparation
Using compressed air
The multimode inlet can also use compressed air cooling with the liquid
N2 inlet cooling option. Requirements for compressed air cooling:
• The compressed air should be free of particulate material, oil, and other
contaminants. These contaminants could clog the inlet's cryo valve and
expansion orifice or impact the proper operation of the GC.
• The required air supply pressure depends on the installed solenoid
valve type. For a multimode inlet with N2 cooling, set the air supply
pressure to 138 to 276 kPa (20 and 40 psig).
While air supplied from tanks can meet these criteria, the consumption
rate of air can be 80 L/min, varying based on supply pressure.
Installation of a compressed air line to the inlet cryo coolant valve
requires the hardware (and appropriate fittings) noted below:
• Use 1/4- inch copper or stainless steel tubing for supply tubing to the
N2 valve
GC, GC/MS, and ALS Site Preparation Guide

Maximum Length of Cables and Hoses
The distance between system modules may be limited by some of the
cabling and the vent or vacuum hoses.
• The length of the Agilent- supplied remote cable is 2 meters (6.6 feet).
• The length of the Agilent- supplied LAN cable is 10 meters (32.8 feet).
• The lengths of the power cords are 2 meters (6.6 feet).
• A quadrupole GC/MS system foreline pump can be located on the
laboratory bench or on the floor. It must be close to the MS because it
is connected by a hose. The hose is stiff and cannot be bent sharply.
The length of the vacuum hose is 130 cm (4.24 feet) from the high
vacuum pump to the foreline pump, while the length of the foreline
pump power cord is 2 meters (6.6 feet).
CAUTION
The supporting surface for the 7200 Q-TOF GC/MS system should be kept relatively
vibration free. Do not put the rough pump on your laboratory bench with the 7200
Q-TOF GC/MS due to the vibration that the pump creates. Vibration can lead to a loss
of mass accuracy and resolution.
• A Q- TOF MS system foreline pump should be located on the floor. It
must be close to the MS because it is connected by a hose. The hose is
stiff and cannot be bent sharply. The length of the vacuum hose is
130 cm (4.24 feet) from the high vacuum pump to the foreline pump,
while the length of the foreline pump power cord is 2 meters (6.6 feet).
• The vacuum hose connecting the Ion Trap MS to the foreline pump is
200 cm (79 in) long.

Hydrogen Carrier Gas
If planning to use hydrogen carrier gas, note that special consideration
apply due to hydrogen’s flammability and chromatographic properties.
• Agilent highly recommends the G3388B Leak Detector to safely check
for leaks.
• Hydrogen carrier gas requires special considerations for supply tubing.
See “Gas Plumbing” on page 86.
• In addition to the supply pressure requirements listed in “Gas
Supplies” on page 82, Agilent also recommends users of hydrogen
carrier gas consider the gas source and purification needs. See the
additional recommendations in “Requirements for hydrogen as a carrier
gas” on page 83.

Do not use extension cords with Agilent instruments. Extension cords normally are
not rated to carry enough power and can be a safety hazard.
Although your GC should arrive ready for operation in your country,
compare its voltage requirements with those listed in Table 31. If the
voltage option you ordered is not suitable for your installation, contact
Agilent Technologies. Note that ALS instruments receive their power from
the GC.
CAUTION
A proper earth ground is required for GC operations. Any interruption of the grounding
conductor or disconnection of the power cord could cause a shock that could result in
personal injury.
GC, GC/MS, and ALS Site Preparation Guide
71
6850 Series GC Site Preparation
To protect users, the metal instrument panels and cabinet are grounded
through the three- conductor power line cord in accordance with
International Electrotechnical Commission (IEC) requirements.
The three- conductor power line cord, when plugged into a properly
grounded receptacle, grounds the instrument and minimizes shock hazard.
A properly grounded receptacle is one that is connected to a suitable
earth ground. Be sure to verify proper receptacle grounding. The GC
requires an isolated ground.
Connect the GC to a dedicated circuit.
Canadian installation
When installing a GC in Canada, make sure your GC’s power supply
circuit meets the following additional requirements:
• The circuit breaker for the branch circuit, which is dedicated to the
instrument, is rated for continuous operation.
• The service box branch circuit is marked as a “Dedicated Circuit.”

Exhaust Venting
Hot air (up to 350 °C) from the oven exits through a vent in the rear.
Allow at least 25 cm (10 in) clearance behind the instrument to dissipate
this air.
WA R N I N G
Do not place temperature-sensitive items (for example, gas cylinders, chemicals,
regulators, and plastic tubing) in the path of the heated exhaust. These items will be
damaged and plastic tubing will melt. Be careful when working behind the
instrument during cool-down cycles to avoid burns from the hot exhaust.
An optional oven exhaust deflector (vertical (G2630- 60710) or horizontal
(G2628- 60800)) is available and may improve oven cooling by deflecting
the exhaust air away from the instrument.
During normal operation of the GC with many detectors and inlets, some
of the carrier gas and sample vents outside the instrument through the
split vent, septum purge vent, and detector exhaust. If any sample
components are toxic or noxious, or if hydrogen is used as the carrier gas,
these exhausts must be vented to a fume hood. Place the GC in the hood
or attach a large diameter venting tube to the outlet for proper ventilation.
To further prevent contamination from noxious gases, attach a chemical
trap to the vent(s).
Vent the GC/MS system externally to the building via an ambient- pressure
vent system, within 460 cm (15 ft) of both the GC split vent and GC/MS
foreline pump, or vent to a fume hood.
Note that an exhaust vent system is not part of the building
environmental control system, which recirculates air.
Exhaust venting must comply with all local environmental and safety
codes. Contact your Environmental Health & Safety (EHS) specialist.

Gas Selection
Table 35 lists gases usable with Agilent GCs and capillary columns. When
used with capillary columns, GC detectors require a separate makeup gas
for optimum sensitivity. The MS and MSD use GC carrier gas.
If using any MS system, use of hydrogen as the carrier gas may require
hardware modifications for best performance. Contact your Agilent service
representative.

When using hydrogen (H2) as the carrier gas or fuel gas, be aware that hydrogen
gas can flow into the GC oven and create an explosion hazard. Therefore, be sure
that the supply is turned off until all connections are made and ensure the inlet and
detector column fittings are either connected to a column or capped at all times
when hydrogen gas is supplied to the instrument.
Hydrogen is flammable. Leaks, when confined in an enclosed space, may create a
fire or explosion hazard. In any application using hydrogen, leak test all
connections, lines, and valves before operating the instrument. Always turn off the
hydrogen supply at its source before working on the instrument.
Please refer to the Hydrogen Safety Guide shipped with your instrument.

Requirements for hydrogen as a carrier gas
Hydrogen can be supplied from a generator or from a cylinder.
Agilent recommends use of a high- quality hydrogen gas generator. A
high- quality generator can consistently produce purity > 99.9999%, and the
generator can include built- in safety features such as limited storage,
limited flow rates, and auto- shutdown. Select a hydrogen generator that
provides low (good) specifications for water and oxygen content.
If using a hydrogen gas cylinder, Agilent recommends use of Gas Clean
Filters to purify the gas. Consider additional safety equipment as
recommended by your company safety personnel.

• If you have not requested option 305 (pre- plumbed tubing), you must
supply pre- cleaned, 1/8- inch copper tubing and a variety of 1/8- inch
Swagelok fittings to connect the GC to inlet and detector gas supplies.
See the Installation Kits for recommended parts.
• Agilent strongly recommends two- stage regulators to eliminate pressure
surges. High- quality, stainless- steel diaphragm- type regulators are
especially recommended.
• On/off valves mounted on the outlet fitting of the two- stage regulator
are not essential but are very useful. Be sure the valves have
stainless- steel, packless diaphragms.
• Agilent strongly recommends installation of shut- off valves at each GC
inlet supply fitting to allow the GC to be isolated for maintenance and
troubleshooting. Order part number 0100- 2144. (Note that some
optional installation kits include one shut- off valve. See Installation
Kits.)
• If you purchased automated valving, the valve actuation requires a
separate pressurized, dry air supply at 380 kPa (55 psig). This air
supply must end in a male fitting compatible with a 1/4- inch id plastic
tube at the GC.
• FID and FPD detectors require a dedicated air supply. Operation may
be affected by pressure pulses in air lines shared with other devices.
• Flow- and pressure- controlling devices require at least
10 psi (138 kPa) pressure differential across them to operate properly.
Set source pressures and capacities high enough to ensure this.
• Situate auxiliary pressure regulators close to the GC inlet fittings. This
ensures that the supply pressure is measured at the instrument (rather
than at the source); pressure at the source may be different if the gas
supply lines are long or narrow.
• Never use liquid thread sealer to connect fittings.
• Never use chlorinated solvents to clean tubing or fittings.
See Basic Tools and Installation Kits for more information.
GC, GC/MS, and ALS Site Preparation Guide

6850 Series GC Site Preparation
Supply tubing for most carrier and detector gases
Use only preconditioned copper tubing (part number 5180- 4196) to supply
gases to the instrument. Do not use ordinary copper tubing—it contains
oils and contaminants.
CAUTION
Do not use methylene chloride or other halogenated solvent to clean tubing that will be
used with an electron capture detector. They will cause elevated baselines and
detector noise until they are completely flushed out of the system.
CAUTION
Do not use plastic tubing for suppling detector and inlet gases to the GC. It is
permeable to oxygen and other contaminants that can damage columns and detectors.
Plastic tubing can melt if near hot exhaust or components.
The tubing diameter depends on the distance between the supply gas and
the GC and the total flow rate for the particular gas. Tubing of 1/8- in
diameter is adequate when the supply line is less than 15 feet (4.6 m)
long.
Use larger diameter tubing (1/4- in) for distances greater then 15 feet
(4.6 m) or when multiple instruments are connected to the same source.
Use larger diameter tubing if high demand is anticipated (for example, air
for an FID).
Be generous when cutting tubing for local supply lines—a coil of flexible
tubing between the supply and the instrument lets you move the GC
without moving the gas supply. Take this extra length into account when
choosing the tubing diameter.
Supply tubing for hydrogen gas
Agilent recommends using new chromatographic quality stainless steel
tubing and fittings when using hydrogen.
88
GC, GC/MS, and ALS Site Preparation Guide
6850 Series GC Site Preparation
• Do not re- use old tubing when installing or switching to hydrogen
carrier gas. Hydrogen gas tends to remove contaminants left on old
tubing by previous gases (by helium, for example). These contaminants
can appear in output as high background noise or hydrocarbon
contamination for several weeks.
• Especially do not use old copper tubing, which can become brittle.
WA R N I N G
Do not use old copper tubing with hydrogen gas. Old copper tubing can become
brittle and create a safety hazard.
Two-stage pressure regulators
To eliminate pressure surges, use a two- stage regulator with each gas
tank. Stainless steel, diaphragm- type regulators are recommended.

6850 Series GC Site Preparation
The type of regulator you use depends on the gas type and supplier. The
Agilent catalog for consumables and supplies contains information to help
you identify the correct regulator, as determined by the Compressed Gas
Association (CGA). Agilent Technologies offers pressure- regulator kits that
contain all the materials needed to install regulators properly.
Pressure regulator-gas supply tubing connections
Use PTFE tape to seal the pipe- thread connection between the pressure
regulator outlet and the fitting to which you connect the gas tubing.
Instrument grade PTFE tape (part number 0460- 1266), from which
volatiles have been removed, is recommended for all fittings. Do not use
pipe dope to seal the threads; it contains volatile materials that will
contaminate the tubing.
Pressure regulators typically end in fittings that must be adapted to the
correct style or size. Table 45 lists parts needed to adapt a standard
1/4- inch male NPT fitting to a 1/8- inch or 1/4- inch Swagelok fitting.

Filters and traps
Using chromatographic- grade gases ensures that the gas in your system is
pure. However, for optimum sensitivity, install high- quality filters or traps
to remove traces of water or other contaminants. After installing a filter,
check the gas supply lines for leaks.
Agilent recommends the Gas Clean Filter system. The Gas Clean Filter
system delivers high purity gases to your analytical instruments, reducing
the risk of column damage, sensitivity loss, and instrument downtime. The
90
GC, GC/MS, and ALS Site Preparation Guide
6850 Series GC Site Preparation
filters are designed for use with the GC, GC/MS, ICP- OES, ICP- MS,
LC/MS, and any other analysis instrument using carrier gas. Six filters are
available, including CO2, oxygen, moisture, and organics trap (charcoal).
Filter types
Each Gas Clean Filter type is designed to filter out a specific impurity
that may exist in the gas supply. The following filter types are available:
• Oxygen - Prevents oxidation of the GC column, septum, liner, and glass
wool.
• Moisture - Delivers fast stabilization times for increased GC
productivity, and prevents hydrolization damage to the stationary phase,
column, liner, glass wool, or septum in the GC.
• Process Moisture - Prevents oxidation of GC components and is safe to
use with acetylene in process GC applications.
• Charcoal - Removes organic compounds and ensures correct
performance of FID detectors in the GC.
• GC/MS - Delivers fast stabilization times for increased GC productivity,
removes oxygen, moisture, and hydrocarbons from the carrier gas for
MS applications, and provides ultimate GC column protection.
Table 46 on page 92 shows recommended filter connection diagrams for
common instrument configurations.

Cryogenic Cooling Requirements
Cryogenic cooling allows you to cool the oven or inlet, including cooling to
setpoints below ambient temperature. A solenoid valve controls the flow of
coolant to the inlet or oven. The oven and inlet can use liquid carbon
dioxide (CO2) as a coolant.
Using carbon dioxide
WA R N I N G
Pressurized liquid CO2 is a hazardous material. Take precautions to protect
personnel from high pressures and low temperatures. CO2 in high concentrations is
toxic to humans; take precautions to prevent hazardous concentrations. Consult
your local supplier for recommended safety precautions and delivery system design.
CAUTION
Liquid CO2 should not be used as a coolant for oven temperatures below –40 °C
because the expanding liquid may form solid CO2—dry ice—in the GC oven. If dry ice
builds up in the oven, it can seriously damage the GC.
Liquid CO2 is available in high- pressure tanks containing liquid. The CO2
should be free of particulate material, oil, and other contaminants. These
contaminants could clog the expansion orifice or affect the proper
operation of the GC.
WA R N I N G
Do not use copper tubing or thin-wall stainless steel tubing with liquid CO2. Both
harden at stress points and may explode.
Additional requirements for the liquid CO2 system include:
• The tank must have an internal dip tube or eductor tube to deliver
liquid CO2 instead of gas (see the figure below).
• Typical liquid CO2 tank pressure will be 4830 to 6900 kPa (700 to
1,000 psi) at a temperature of 25 °C.
GC, GC/MS, and ALS Site Preparation Guide
95
6850 Series GC Site Preparation
• Use 1/8- inch diameter heavy- wall stainless steel tubing for supply
tubing. The tubing should be between 1.5 and 15 m (5 and 50 feet)
long. (Agilent part number 7157- 0210, 20 ft)
• Coil and fasten the ends of the tubing to prevent it from “whipping” if
it breaks.
• Do not install a pressure regulator on the CO2 tank, as vaporization
and cooling would occur in the regulator instead of the oven.
• Do not use a padded tank (one to which another gas is added to
increase the pressure).

Maximum Length of Cables
The distance between system modules may be limited by some of the
cabling and the vent or vacuum hoses.
• The length of the Agilent- supplied remote cable is 2 meters (6.6 feet).
• The length of the Agilent- supplied LAN cable is 10 meters (32.8 feet).
• The lengths of the power cords are 2 meters (6.6 feet).
• A quadrupole GC/MS system foreline pump can be located on the
laboratory bench or on the floor. It must be close to the MS because it
is connected by a hose. The hose is stiff and cannot be bent sharply.
The length of the vacuum hose is 130 cm (4.24 feet) from the high
vacuum pump to the foreline pump, while the length of the foreline
pump power cord is 2 meters (6.6 feet).

Do not use extension cords with Agilent instruments. Extension cords normally are
not rated to carry enough power and can be a safety hazard.
Although your GC should arrive ready for operation in your country,
compare its voltage requirements with those listed in Table 52. If the
voltage option you ordered is not suitable for your installation, contact
Agilent Technologies. Note that ALS instruments receive their power from
the GC.
Grounding
CAUTION
A proper earth ground is required for GC operations. Any interruption of the grounding
conductor or disconnection of the power cord could cause a shock that could result in
personal injury.
To protect users, the metal instrument panels and cabinet are grounded
through the three- conductor power line cord in accordance with
International Electrotechnical Commission (IEC) requirements.
GC, GC/MS, and ALS Site Preparation Guide
109
7820 MSD Site Preparation
The three- conductor power line cord, when plugged into a properly
grounded receptacle, grounds the instrument and minimizes shock hazard.
A properly grounded receptacle is one that is connected to a suitable
earth ground. Be sure to verify proper receptacle grounding.
Connect the GC to a dedicated circuit.

Exhaust Venting
Hot air (up to 425 °C) from the oven exits through a vent in the rear.
Allow at least 25 cm (10 in) clearance behind the instrument to dissipate
this air.
WA R N I N G
Do not place temperature-sensitive items (for example, gas cylinders, chemicals,
regulators, and plastic tubing) in the path of the heated exhaust. These items will be
damaged and plastic tubing will melt. Be careful when working behind the
instrument during cool-down cycles to avoid burns from the hot exhaust.
During normal operation of the GC with many detectors and inlets, some
of the carrier gas and sample vents outside the instrument through the
split vent, septum purge vent, and detector exhaust. If any sample
components are toxic or noxious, or if hydrogen is used as the carrier gas,
these exhausts must be vented to a fume hood. Place the GC in the hood
or attach a large diameter venting tube to the outlet for proper ventilation.
To further prevent contamination from noxious gases, attach a chemical
trap to the vent(s).
Vent the GC/MS system externally to the building via an ambient- pressure
vent system, within 460 cm (15 ft) of both the GC split vent and GC/MS
foreline pump, or vent to a fume hood.
Note that an exhaust vent system is not part of the building
environmental control system, which recirculates air.
Exhaust venting must comply with all local environmental and safety
codes. Contact your Environmental Health & Safety (EHS) specialist.

Gas and Reagent Selection
The 7820 MSD system (GC and MSD) requires helium or hydrogen carrier
gas.
If using any MS system, use of hydrogen as the carrier gas may require
hardware modifications for best performance. Contact your Agilent service
representative.
NOTE
WA R N I N G
Nitrogen and Argon/Methane are generally not suitable for GC/MS carrier gas.
When using hydrogen (H2) as the carrier gas or fuel gas, be aware that hydrogen
gas can flow into the GC oven and create an explosion hazard. Therefore, be sure
that the supply is turned off until all connections are made and ensure the inlet and
detector column fittings are either connected to a column or capped at all times
when hydrogen gas is supplied to the instrument.
Hydrogen is flammable. Leaks, when confined in an enclosed space, may create a
fire or explosion hazard. In any application using hydrogen, leak test all
connections, lines, and valves before operating the instrument. Always turn off the
hydrogen supply at its source before working on the instrument.
Please refer to the Hydrogen Safety Guide shipped with your instrument.

Gas and Reagent Purity
Agilent recommends that carrier and detector gases be 99.9995% pure. See
Table 56. Air needs to be zero grade or better. Agilent also recommends
using high quality traps to remove hydrocarbons, water, and oxygen.

Gas Supplies
General requirements
Supply instrument gases using tanks, an internal distribution system, or
gas generators. If used, tanks require two- stage pressure regulators with
packless, stainless steel diaphragms. The instrument requires 1/8- inch
Swagelok connections to its gas supply fittings.
NOTE
Plumb the gas supply tubing/regulators so that one 1/8-inch Swagelok female connector is
available for each gas needed at the instrument.

Requirements for hydrogen as a carrier gas
Hydrogen can be supplied from a generator or from a cylinder.
Agilent recommends use of a high- quality hydrogen gas generator. A
high- quality generator can consistently produce purity > 99.9999%, and the
generator can include built- in safety features such as limited storage,
limited flow rates, and auto- shutdown. Select a hydrogen generator that
provides low (good) specifications for water and oxygen content.
If using a hydrogen gas cylinder, Agilent recommends use of Gas Clean
Filters to purify the gas. Consider additional safety equipment as
recommended by your company safety personnel.

7820 MSD Site Preparation
• If you have not requested option 305 (pre- plumbed tubing), you must
supply pre- cleaned, 1/8- inch copper tubing and a variety of 1/8- inch
Swagelok fittings to connect the GC to inlet and detector gas supplies.
See the Installation Kits for recommended parts.
• Agilent strongly recommends two- stage regulators to eliminate pressure
surges. High- quality, stainless- steel diaphragm- type regulators are
especially recommended.
• On/off valves mounted on the outlet fitting of the two- stage regulator
are not essential but are very useful. Be sure the valves have
stainless- steel, packless diaphragms.
• Agilent strongly recommends installation of shut- off valves at each GC
inlet supply fitting to allow the GC to be isolated for maintenance and
troubleshooting. Order part number 0100- 2144. (Note that some
optional installation kits include one shut- off valve. See Installation
Kits.)
• If you purchased automated valving, the valve actuation requires a
separate pressurized, dry air supply at 380 kPa (55 psig). This air
supply must end in a male fitting compatible with a 1/4- inch id plastic
tube at the GC.
• FID, FPD, and NPD detectors require a dedicated air supply. Operation
may be affected by pressure pulses in air lines shared with other
devices.
• Flow- and pressure- controlling devices require at least
10 psi (138 kPa) pressure differential across them to operate properly.
Set source pressures and capacities high enough to ensure this.
• Situate auxiliary pressure regulators close to the GC inlet fittings. This
ensures that the supply pressure is measured at the instrument (rather
than at the source); pressure at the source may be different if the gas
supply lines are long or narrow.
• Never use liquid thread sealer to connect fittings.
• Never use chlorinated solvents to clean tubing or fittings.
122
GC, GC/MS, and ALS Site Preparation Guide
7820 MSD Site Preparation
Supply tubing for most carrier and detector gases
Use only preconditioned copper tubing (part number 5180- 4196) to supply
gases to the instrument. Do not use ordinary copper tubing—it contains
oils and contaminants.
CAUTION
Do not use methylene chloride or other halogenated solvent to clean tubing that will be
used with an electron capture detector. They will cause elevated baselines and
detector noise until they are completely flushed out of the system.
CAUTION
Do not use plastic tubing for suppling detector and inlet gases to the GC. It is
permeable to oxygen and other contaminants that can damage columns and detectors.
Plastic tubing can melt if near hot exhaust or components.
The tubing diameter depends on the distance between the supply gas and
the GC and the total flow rate for the particular gas. Tubing of 1/8- in
diameter is adequate when the supply line is less than 15 feet (4.6 m)
long.
Use larger diameter tubing (1/4- in) for distances greater then 15 feet
(4.6 m) or when multiple instruments are connected to the same source.
Use larger diameter tubing if high demand is anticipated (for example, air
for an FID).
Be generous when cutting tubing for local supply lines—a coil of flexible
tubing between the supply and the instrument lets you move the GC
without moving the gas supply. Take this extra length into account when
choosing the tubing diameter.
Supply tubing for hydrogen gas
Agilent recommends using new chromatographic quality stainless steel
tubing and fittings when using hydrogen.
GC, GC/MS, and ALS Site Preparation Guide
123
7820 MSD Site Preparation
• Do not re- use old tubing when installing or switching to hydrogen
carrier gas. Hydrogen gas tends to remove contaminants left on old
tubing by previous gases (by helium, for example). These contaminants
can appear in output as high background noise or hydrocarbon
contamination for several weeks.
• Especially do not use old copper tubing, which can become brittle.
WA R N I N G
Do not use old copper tubing with hydrogen gas. Old copper tubing can become
brittle and create a safety hazard.
Two-stage pressure regulators
To eliminate pressure surges, use a two- stage regulator with each gas
tank. Stainless steel, diaphragm- type regulators are recommended.

124
GC, GC/MS, and ALS Site Preparation Guide
7820 MSD Site Preparation
The type of regulator you use depends on the gas type and supplier. The
Agilent catalog for consumables and supplies contains information to help
you identify the correct regulator, as determined by the Compressed Gas
Association (CGA). Agilent Technologies offers pressure- regulator kits that
contain all the materials needed to install regulators properly.
Pressure regulator-gas supply tubing connections
Use PTFE tape to seal the pipe- thread connection between the pressure
regulator outlet and the fitting to which you connect the gas tubing.
Instrument grade PTFE tape (part number 0460- 1266), from which
volatiles have been removed, is recommended for all fittings. Do not use
pipe dope to seal the threads; it contains volatile materials that will
contaminate the tubing.
Pressure regulators typically end in fittings that must be adapted to the
correct style or size. Table 63 lists parts needed to adapt a standard
1/4- inch male NPT fitting to a 1/8- inch or 1/4- inch Swagelok fitting.

Filters and traps
Using chromatographic- grade gases ensures that the gas in your system is
pure. However, for optimum sensitivity, install high- quality filters or traps
to remove traces of water or other contaminants. After installing a filter,
check the gas supply lines for leaks.
Agilent recommends the Gas Clean Filter system. The Gas Clean Filter
system delivers high purity gases to your analytical instruments, reducing
the risk of column damage, sensitivity loss, and instrument downtime. The
GC, GC/MS, and ALS Site Preparation Guide
125
7820 MSD Site Preparation
filters are designed for use with the GC, GC/MS, ICP- OES, ICP- MS,
LC/MS, and any other analysis instrument using carrier gas. Six filters are
available, including CO2, oxygen, moisture, and organics trap (charcoal).
Filter types
Each Gas Clean Filter type is designed to filter out a specific impurity
that may exist in the gas supply. The following filter types are available:
• Oxygen - Prevents oxidation of the GC column, septum, liner, and glass
wool.
• Moisture - Delivers fast stabilization times for increased GC
productivity, and prevents hydrolization damage to the stationary phase,
column, liner, glass wool, or septum in the GC.
• Process Moisture - Prevents oxidation of GC components and is safe to
use with acetylene in process GC applications.
• Charcoal - Removes organic compounds and ensures correct
performance of FID detectors in the GC.
• GC/MS - Delivers fast stabilization times for increased GC productivity,
removes oxygen, moisture, and hydrocarbons from the carrier gas for
MS applications, and provides ultimate GC column protection.
Table 64 on page 127 shows recommended filter connection diagrams for
common instrument configurations.
