In addition to the information in this chapter, you must also obey the building and safety
rules and regulations for construction that apply in your area.
Entrance
The entrance to your facility and the width of all hallways, elevators, and
doorways should be at least 92 cm (37 in.).1 However, you should allow additional
room for maneuvering the system around corners, into elevators, or through
doorways.
The FOCUS GC and accessories are shipped in a container with the following
dimensions:
l—92 cm (37 in.), w—76 cm (30 in.), h—88 cm (35 in.)
The container and its contents weigh approximately 65 kg (145 lbs). Other
modules, such as the computer, monitor, and options, are shipped in their own
containers. Their dimensions and weights are less than those of the FOCUS GC
container.

Space and Load Requirements
Space and Load Requirements
We recommend the following space allowances for the area around the gas
chromatograph:
•
The working area should be at least 1.5 m (5 ft) wide.
•
The working area should be 1.5 m (5 ft) deep. The depth includes a 75 cm
(30 in.) bench for the gas chromatograph.
•
The area behind the instrument should be a minimum of 30 cm (12 in.).
Provide enough space around the instrument for operators to work beside it and in
front of it. Keep in mind that the GC oven vents to the rear. Any material exposed
to the oven exhaust must withstand repeated exposure to temperatures of up to
350 °C (660 °F).
The space requirements and weights for the standard system components are
given in Table 1-1. Similar information for FOCUS GC optional instruments is
provided in Table 1-2.
The FOCUS GC system should be placed on a workbench that has minimum
dimensions of 0.75 × 2 m (2.5 × 6 ft.). The workbench must also be capable of
supporting the weight of the data system computer or computing integrator, 27 kg
(60 lb), plus the weight of any options. Be sure there is at least 16 cm (6 in.) of
space behind the workbench for connections. In addition, there must be at least
92 cm (36 in.) of vertical clearance from the top of the FOCUS GC system.
Therefore, you should avoid placing the instrument below cabinets or shelves.
NOTE
To keep the data system computer or integrator close to the electrical connections, we
recommend placing it on the right side of the GC.

Power Requirements
Power Requirements
It is your responsibility to provide an acceptable source of power. You should
provide a dedicated power line with a circuit breaker capable of withstanding the
power ratings listed in the following sections.
120 V ac Power Requirements
For FOCUS GC systems installed in the US and other countries using 120 V ac
power, the minimum power requirements are as follows:
•
120 V ac +6, –10%
•
frequency of 50/60 Hz ± 2 Hz; 1600 VA
•
three duplex outlets (single-phase power) with a minimum power rating of
20 A at each duplex outlet
•
earth ground hard-wired to the main panel
230 V ac Power Requirements
For FOCUS GC systems installed in countries using 230 V ac power, the
minimum power requirements are as follows:
•
230 V ac ± 10%
•
frequency of 50/60 Hz ± 2 Hz; 1600 VA
•
three duplex outlets, with a minimum power rating of 16 A at each duplex
outlet
•
earth ground hardwired to the main panel
Power Quality
The quality of power supplied to your FOCUS GC system must be stable and
within the specifications listed in this guide. The line voltage must be free of
fluctuation due to slow changes in the average voltage, surges, sags, transients,
and harmonics.
Site Preparation and Installation Manual
23
Chapter 1
Laboratory Preparation
Power Requirements
The FOCUS GC system operates in an Overvoltage Category II environment, as
defined in International Standard EN 61010.
Below are definitions for the most common voltage disturbances:
Slow average is a gradual, long-term change in average root mean square (RMS)
voltage level, with typical durations greater than 2 s.
Sags and surges are sudden changes in average RMS voltage level, with typical
durations between 50 µs and 2 s.
Transients (or impulses) are brief voltage surges of up to several thousand volts,
with durations of less than 50 µs.
Harmonic distortion is a high-frequency disturbance that appears as distortion of
the fundamental sine wave. Total harmonic distortion should be less than 3%.
Effects of Voltage Disturbances
Constant high line voltage or surges in voltage can cause overheating and
component failures. Constant low line voltage or sags in voltage can cause the
system to function erratically. Transients, even of a few microseconds duration,
can cause electronic devices to fail catastrophically or to degrade, shortening their
lives significantly. Harmonic distortion can cause noise in power supply lines and
degrade the performance of the instrument. Therefore, it is important to establish
the quality of the line power in your laboratory prior to the installation of your
FOCUS GC system.
NOTE
The interconnected power outlets for the FOCUS GC system require a common point to
one ground connector. If there are two such points, with each connected to separate
external grounds, noise current will flow through the ground system via the ground loop
that is formed.
Wall Outlets
The power cable from the FOCUS GC is approximately 3 m (9 ft) long.
NOTE
24
Use an Uninterruptible Power Source (UPS) to protect your data system against possible
loss due to power outages. At this time, we do not recommend using a UPS with the GC.
Site Preparation and Installation Manual
Chapter 1
Laboratory Preparation
Power Requirements
Most UPS systems are not designed to provide high-quality distortion-free power for
scientific equipment.
The 120 V ac systems are fitted with U.S. standard National Electronics
Manufacturers Association (NEMA) 5-20P power plugs. A NEMA 5-20P power
plug and its corresponding outlet are rated at 20 A and 125 V ac.
The power cables from the personal computer, monitor, and printer are
approximately 2 m (6 ft) long. The 120 V ac systems are fitted with NEMA 5-15P
plugs. For optional instruments, the plug requirements may vary. Refer to your
product’s user manual for specifications.
Figure 1-1 shows the NEMA power plugs and outlets.

Operating Environment
Technical Assistance
Occasionally, unacceptable quality in line power sources may adversely affect the
operation of a FOCUS GC system. It is the user’s responsibility to correct line
voltage problems.
Specifying power conditioning equipment is a complex task that is best handled
by a company or consultant specializing in that field.
Contact your Thermo Fisher Scientific CSE for assistance in locating a power
consultant. Refer to Appendix B Customer Communication for a Thermo Fisher
Scientific office in your area.
Operating Environment
The operating environment in your laboratory is affected by such factors as
temperature, humidity, particulate matter, and electrostatic discharge. It is your
responsibility to provide an acceptable operating environment for your FOCUS
GC system.
Attention to the operating environment will ensure continued high performance of
your gas chromatograph.
Temperature
The room temperature must be maintained between 18 and 35 °C (65 and 95 °F),
and should remain consistent. As the laboratory temperature increases, system
reliability decreases.
NOTE
All electronic components generate heat while operating. This heat must be dissipated to
the surrounding air for the components to operate reliably.
Cooling Requirements
There must be a good flow of air around the system, and the air conditioning must
be capable of maintaining a constant temperature (within the operational limits).
Any costs for air conditioning are more than offset by good sample throughput
and reduced repair costs.

Operating Environment
Oven Exhaust
The GC oven exhaust vents are in the rear of the instrument. Hot air
(350 °C [660 °F]) exits through these vents during GC operation. As stated under
Space and Load Requirements in this chapter, there should be at least 30 cm (12
in.) free space behind the instrument to allow the exhaust to dissipate. Any
material exposed to the oven exhaust must be able to withstand repeated exposure
to temperatures of up to 350 °C (660 °F).
WARNING! Oven exhaust can cause severe burns. Avoid working behind the instrument when
the oven vents during cooling-down cycles. Do not expose gas tanks or bottles,
chemicals, regulators, electrical cords, or other temperature-sensitive items to oven
exhaust.
Altitude
The maximum operating altitude for the FOCUS GC is 2,000 meters above sea
level.
Humidity
The relative humidity of the operating environment must be between 5 and 95%
with no condensation.
Operating your FOCUS GC system in low humidity will cause the accumulation
and discharge of static electricity, which shortens the life of electronic
components. Operating your GC system in high humidity causes condensation,
which can lead to short circuits. High humidity also blocks traps on cooling fans.
We recommended you equip your laboratory with temperature and humidity
monitors to ensure your laboratory is always within the required temperature and
humidity specifications.
Particulate Matter
The air in your laboratory must not have excessive dust, smoke, or other
particulate matter. The air should contain fewer than 1,000,000 particles per cubic
meter (100,000 particles per cubic foot) larger than 5 µm.
Site Preparation and Installation Manual

Chapter 1
Laboratory Preparation
Operating Environment
Dust can clog the air traps causing a reduction in air flow around electronic
components. Dust will also form a layer on electronic components that will act as
an insulating blanket, reducing the transfer of heat from the components to the
surrounding air.
Electrostatic Discharge
The FOCUS GC, with all its covers in place, is not susceptible to static discharge.
However, laboratory conditions that expose instrumentation and laboratory
personnel to repeated high levels of static discharge should be considered a safety
hazard.
Therefore, we recommend you take the following precautions, especially if you
are operating your system at the lower end of the relative humidity specification
listed above.
•
Use a static-dissipating floor covering (such as tile or conductive linoleum) in
the room housing your instrument.
•
Use laboratory chairs covered with natural fibers or other static-dissipating
material.
•
Wear laboratory coats and clothing made from natural fibers or other staticdissipating material.
•
Do not place polystyrene (foam) cups or packing materials on the instrument.
Vibration
Place your instruments on surfaces that are free of vibration. Be aware of
vibrations caused by equipment in adjoining locations.
Lighting
Overhead lighting is recommended to light your work area.

Exhaust System
Other Environmental Factors
The FOCUS GC operates in an environment where normally only non-conductive
pollution occurs, but in which temporary conductivity due to condensation must
be expected. This is a Pollution Degree 2 environment, as specified in
International Standard EN 61010.
Exhaust System
Laboratories meeting the heating and cooling requirements specified in this
manual will sufficiently circulate lab air to prevent accumulation of gases and
fumes vented during normal GC use. Extensive leaks in plumbing lines to the GC
may present hazards. Be sure to follow all local codes regulating plumbing of
gases.

Gas and Plumbing Requirements
Gas and Plumbing Requirements
You must provide the gas supplies for your gas chromatograph. Be sure to order
your gases and regulators far enough ahead of time to have them ready for the GC
installation process.
WARNING! All Thermo Fisher Scientific gas chromatographs are designed to use an inert gas
as the carrier gas. If you wish to use hydrogen as a carrier gas, you must install a
hydrogen sensor. Contact a Thermo Fisher Scientific sales representative if you
plan to use hydrogen as the carrier gas in your new FOCUS GC. If you don’t have the
hydrogen sensor, you must use an inert carrier gas.

Laboratory Preparation
Gas Purity
If possible, you should use only instrument or chromatographic purity grade gases
in your FOCUS GC.
Traps
UHP (Ultra-High Purity) gases should not contain impurities above 1 ppm.
Impurities below 1 ppm generally do not require purification. Gases with higher
impurity levels may require oxygen and hydrocarbon traps. A number of GC
supply and accessory companies carry a variety of traps for gases.
See Figure 4-2, Gas Trap Order, on page 57, for the correct trap installation
sequence. For more information on gas purification, contact your local Thermo
Fisher Scientific CSE.
Moisture Traps
Water in the carrier or fuel gas may damage the gas chromatograph column and
contaminate the FOCUS GC system. Water content should be less than 1 ppm in
all cases. If you are using multiple traps, install the moisture trap closest the gas
supply, before the hydrocarbon and the oxygen trap.
Hydrocarbon Traps
Hydrocarbon traps remove organic materials from gases. If you are using multiple
traps, install the hydrocarbon trap after the moisture trap, but before the oxygen
trap.
Oxygen Traps
Oxygen content in the carrier and gas lines should be less than 1 ppm. To achieve
a level of oxygen of less than 1 ppm, install an oxygen-removing trap in the
carrier gas line between the gas tank and the GC. If you are using multiple traps,
the oxygen trap should be the last trap in the series.
Purity Requirements
The following sections describe the minimum requirements for gases used in your
gas chromatograph system. Always consider using UHP 99.999% pure gases
when available.
Site Preparation and Installation Manual
33
Chapter 1
Laboratory Preparation
Gas and Plumbing Requirements
Helium
For carrier gas: 99.995%1 high purity, with less than 1.0 ppm each of water,
oxygen, and total hydrocarbons after purification. One full-size tank that has an
outlet pressure of 400–700 kPa (60–100 psi). Use a regulator with a CGA 580
connection or equivalent. Use water, oxygen, and hydrocarbon traps.
Hydrogen
For carrier or detector fuel gas: 99.995%1 high purity, with less than 1.0 ppm of
total hydrocarbons after purification. One full-size tank that has an outlet pressure
of 400–700 kPa (60–100 psi). Use a regulator with a CGA 350 connection or
equivalent. Use water, oxygen and hydrocarbon traps.
Air
For detector fuel gas: 99.995%1 high purity. Use a regulator with a CGA 0590
connection or equivalent. Air compressors are not acceptable because they do not
meet pressure, water, and hydrocarbon requirements.
Nitrogen
For carrier or make-up gas: 99.995% high purity, with less than 1.0 ppm of total
hydrocarbons after purification. Use a regulator with a CGA 0580 connection or
equivalent.
Argon
For carrier or make-up gas: 99.995%1 high purity. Use a regulator with a CGA
350 connection or equivalent.
Gas Regulators and Fittings
Gas tanks may be equipped with either single- or dual-stage regulators that
contain stainless steel diaphragms. The regulator output pressure should be
adjustable from 300 to 700 kPa (45–100 psi). Each regulator should be equipped
with a 1/8-in. Swagelok compression fitting, or equivalent. Figure 1-3 shows a
dual-stage gas regulator with 1/8-in. fittings.

Figure 1-3. Dual-Stage Gas Regulator
Verify with your gas supplier the type of CGA fitting on the gas bottles you order.
Be sure these fittings match the regulators described in Purity Requirements in
this chapter. If not, contact your gas supplier or your area Thermo Fisher
Scientific sales representative to make the appropriate changes.
Secondary Gas Regulators
Because secondary regulation of carrier, fuel, and make-up gases may be provided
downstream of the cylinder regulator, a single- or dual-stage regulator is
acceptable, but it must use a stainless steel diaphragm.
Gas Tanks
Gas tanks should be placed where they cannot damage cables or gas lines. Use
standard safety practices for securing gas tanks and bottles. Gas supply lines
should terminate with 1/8-in. female Swagelok connectors.
Stored gases should be placed in an area where a wide temperature variation will
not occur. Don’t forget to plan for gas cylinder storage when preparing your
laboratory.
WARNING! Do not place gas tanks in the path of the GC oven exhaust.

How to Use Swagelok Tube Fittings
The Swagelok fitting consists of four components: a Swagelok nut, a back ferrule,
a front ferrule, and an inlet body. It becomes a five-piece connection when affixed
to the tubing. The two ferrules merge when the nut is tightened, forming a safe
and leak-free seal between the tubing and body.
Use the following procedure to connect tubing using Swagelok fittings:
1. Place a Swagelok nut over the end of the tubing.
2. Place a back ferrule over the end of the tubing.
3. Place a front ferrule over the end of the tubing. If you are using tubing smaller
than 1/8-in., make sure the tubing extends only 5 mm past the front ferrule.
This will prevent damage to the fritted filter inside the inlet manifold.

Chapter 4
Plumbing the Gas Supply to the GC
Using Hydrogen
WARNING! Hydrogen is a dangerous gas that, when mixed with air, may create an explosive
mixture. The use of hydrogen as a carrier gas requires the operator’s extreme
caution. Special precautions must be taken because of the risk of explosion. The
gas chromatograph must be equipped with a hydrogen sensor if you use hydrogen
as a carrier gas. Refer to Using Hydrogen on page 54 for more information.
Using Hydrogen
The use of hydrogen as a carrier gas or as fuel for certain flame detectors requires
the operator’s strict attention and compliance with special precautions due to the
hazards involved.
Hydrogen is a dangerous gas, particularly in an enclosed area when it reaches a
concentration corresponding to its lower explosion level (4% in volume). When
mixed with air it can create an explosive mixture. An explosion hazard could
develop in the GC oven when hydrogen is used as a carrier gas if oven elements
are not perfectly connected to each other, or if the connection materials are worn
out, broken, or otherwise faulty.
Use the following safety precautions when using hydrogen:
•
Ensure that all hydrogen cylinders comply with the safety requirements for
proper use and storage. Hydrogen cylinders and delivery systems must couply
with local regulations.
•
Make sure the gas supply is turned completely off when connecting hydrogen
lines.
•
Perform a bubble test to ensure that the hydrogen lines are leak-tight before
using the instrument. Perform this test after the pressure test described in the
Testing for Leaks portion of this chapter. Repeat this test to eliminate all leaks.
•
Ensure your GC column oven has a Thermo Fisher Scientific hydrogen
sensor. A hydrogen sensor continuously monitors the hydrogen level in the
GC column oven.
If your GC oven does not have a hydrogen sensor already installed, contact
your Thermo Fisher Scientific sales representative. To comply with
54
Site Preparation and Installation Manual
Chapter 4
Plumbing the Gas Supply to the GC
Using Hydrogen
instrument safety requirements, a Thermo Fisher Scientific CSE or authorized
service technician should install the sensor.
If you plan to use a sensor other than the recommended Thermo Fisher
Scientific sensor, you must verify its ability to perform the functions listed
above before installing it. It must comply with your local safety regulations,
or with the IEC 610101 regulations if local regulations do not exist.
Using the Hydrogen Sensor
The lower limit of the hydrogen sensor is 0.5% in volume. You should adjust the
detection threshold to 1% in volume, which is 25% of the hydrogen lower limit of
explosion (4% in volume).
In cases where the connections begin to leak or the column breaks, the sensor
alerts the operator. Then it automatically cuts off the gas supply and heating to the
active zones, and sweeps the column oven with forced air ventilation.
If the sensor detects anomalies or leaks during GC operation due to instrument
malfunction, the operator must immediately:
•
close the hydrogen supply
•
switch off the gas chromatograph
•
air out the room
The reliability of the sensor depends on careful maintenance. After the sensor is in
use, you must periodically check its operating performance and calibration as
recommended by the manufacturer. Refer to your hydrogen sensor’s instruction
manual for maintenance guidelines.
WARNING! Never use hydrogen in your FOCUS GC system unless your GC oven has a
hydrogen sensor installed.
NOTE
Thermo Fisher Scientific CSEs are not authorized to install or repair any instrument using
hydrogen as a carrier gas unless the instrument is equipped with the appropriate sensor.

Plumbing the Gas Supply to the GC
Building the Gas Lines
Use the following procedure to connect tubing to the gas supply control valves:
1. Make sure the initial supply valves (on cylinders or panel board) are turned
off.
2. Determine the length of tubing you need. Use only enough tubing to connect
the instrument to the gas supplies, but allow enough slack to allow the GC to
be moved at least 40 cm (16 in.) from other equipment. This allows enough
room to perform column connections and system maintenance. Also, be sure
to account for tee connections.
3. Use a tubing cutter to cut the tubing.
4. Use a Swagelok tube fitting to attach the tubing to the gas outlet. Refer to
How to Use Swagelok Tube Fittings in Chapter 3, Before You Begin…, for
instructions on using Swagelok fittings.
Adding Traps to the Gas Supply
You may wish to use traps, such as moisture or oxygen traps, in your gas supply
line. Traps are especially necessary if you are unsure of the purity of your gas
supplies. Refer to Gas and Plumbing Requirements in Chapter 1, Laboratory
Preparation, for more information about gas purity requirements and appropriate
traps for your GC. Figure 4-2 shows the proper order of traps in a gas supply line.
Refer to your trap’s instruction manual for specific purging and installation
requirements.

Purging Gas Lines
Use the following procedure to attach traps to your gas line:
1. Determine the location for the trap in your supply line. Figure 4-2 shows the
recommended trap order.
2. Use a tubing cutter to cut the tubing to the desired length.
3. Turn the gas regulator supply handle counterclockwise to reduce line
pressure, then turn the gas supply on and increase the pressure to 35 kPa
(5 psi) for about 15 seconds to purge the line of any unwanted debris.
4. Turn the gas supply off.
5. Use a 1/8" Swagelok fitting to connect the trap inlet to the gas supply tubing
coming from the tank.
6. Turn the gas supply on to 35 kPa (5 psi) for about 30 seconds.
7. Turn the gas supply off.
8. Connect tubing to the trap outlet with a 1/8" Swagelok fitting.
Follow this procedure for all traps you wish to add to your gas supply line.
Purging Gas Lines
You must purge the lines any time you make a cut in the tubing during the gas line
assembly process. This will clear them of any debris from the cut. You will also
need to purge the completely assembled gas lines, including any traps you plan to
use, before you connect the your gas supply to the FOCUS GC.
Use the following procedure to purge the gas lines:
1. Turn the gas supply on, and set the pressure to 35 kPa (5 psi).
2. Allow the line to purge for 10 minutes.
3. Turn off the gas supply.

Testing for Leaks
Testing for Leaks
Once you have connected the gas supply to the GC inlet you need to test the
supply lines for leaks. Turn on your gas supply and use the following information
to set the gas pressures for the leak test.
•
Set the carrier gas pressure to approximately 50 kPa (7 psi) higher than the
maximum pressure of the GC regulator.
•
Set the detector gas pressures to approximately 350 kPa (50 psi).
•
Next you need to check all Swagelok ® fittings for leaks. Use the following
procedure to check the fittings for leaks:
1. Use a handheld electronic leak detector compatible with the carrier gas in use
to check each fitting for leaks.
2. If you detect a leak, tighten the connection and retest it.
3. Repeat this process until all Swagelok® connections are leak free.
WARNING! Do not use liquid soap leaks sensor for leaks. Liquid soap leaks sensor
contaminates your system.
A mixture of 50% H2O/50% methanol or isopropyl alcohol may be used as a liquid
leak detector. Never use liquid leak detectors on or around electronic pneumatic
circuits.
