Proper Use
DANGER !
Explosion hazard!
The unit is not designed for extraction and metabolization procedures employing
organic solvents.
Warning !
Observe all operating instructions!
Since sample composition is generally not precisely defined, a certain residual risk
exists when performing pressure digestion processes. Careful working practices
and conscious compliance with safety regulations can only minimize this risk, not
totally eliminate it. Due to different degrees of mixing, even identical samples can
exhibit totally different behaviors during the course of the reaction!
Please strictly comply with the operating instructions, particularly when handling
the pressure vessels, that is, when removing and opening the vessels. Incorrect
handling of the hot, pressurized vessels can result in injuries from escaping acid
vapors!
The speedwave microwave digestion system has been designed to perform
chemical digestion procedures under extreme pressure and temperature conditions
in chemical laboratories. Digestion is understood to mean the decomposition of a
solid material by means of a suitable digestion reagent at increased temperature in
a vessel that is permeable with regard to microwaves. The digestion solutions are
directly heated through the absorption of the microwave radiation by the polar digestion reagent, which generally also contains ionic components.
Digestion reagents used include nitric acid (65%), hydrochloric acid, hydrofluoric
acid, phosphoric acid, and sulfuric acid, as well as mixtures of these acids. The
maximum initial weight for organic compounds depends on the digestion vessel being used and the sample’s carbon content, must always be observed. The use of
organic solvents is strictly prohibited in microwaves since the spontaneous combustion of any solvent vapors that escape into the oven chamber cannot be precluded.
Heating in the pressure vessel results in digestion temperatures in excess of 200
°C (392°F). The speedwave has been specially developed for sample preparation
for AAS and ICP spectroscopy procedures. Very temperature spikes >280 °C
(>536°F) such as can occasionally occur during the course of exothermic reactions
can result in irreversible damage to the Teflon vessels. Since such scorching cannot always be avoided, even with optimum microwave power regulation, damage of
this kind is excluded from the warranty! When quartz glass inserts are employed,
the greatest care must be taken when handling the glass as even the slightest
amount of damage to the surface can greatly diminish surface strength. For this
reason, glass components are excluded from the warranty!
Adapters for evaporating and concentrating digestion solutions are optionally available for all vessel types.
Qualified handling and, possibly, proper transport, storage, set-up, and use, as well
as conscientious maintenance are all prerequisites for the trouble-free and safe
operation of the speedwave microwave digestion system.

General Safety Information
Performing microwave digestion procedures involves taking into account various
safety precautions which go beyond those for general laboratory practices. The following general safety information should therefore be read carefully prior to using
the system, and should be observed at all times.
The following information must be complied with when working with the associated

Always wear safety glasses/goggles and protective gloves during work which may
involve contact with chemicals, that is, when working with acids, pressure vessels,
during cleaning, etc.!
DANGER !
Explosion hazard!
Do not use perchloric acid.
No organic solvents (alcohols, hydrocarbons, etc.) may be placed in the pressure
vessels or the microwave.
Highly reactive substances which spontaneously react at higher temperatures or in
the presence of oxidizing agents or which may be nitrated and are potentially explosive may not be digested in the microwave. Examples of such substances include: explosives (TNT, etc.), perchlorates, ether, pyrophoric substances, etc.

Pressure vessels!
Use only digestion vessels and spare parts authorized by Berghof Products + Instruments GmbH for use with the speedwave. These can be obtained either from
your local dealer or directly from Berghof Products + Instruments GmbH (Refer to
the “Repairs / Customer Service” section for contact addresses).
Always wear safety glasses/goggles and protective gloves when working with the
pressure vessels!
Note any changes in the appearance of the pressure vessel which could indicate
possible material fatigue, e.g., deformation of the vessel, difficulty screwing on
lids, etc. even when the vessel is cold and not under pressure. All such vessels
should be immediately returned to Berghof Products + Instruments GmbH for inspection.
Never attempt to use force to open the vessels. Never use tools to open the vessels!
The pressure vessels are equipped with a rupture disc which produces a spontaneous pressure release upwards through the screw-on tube connections in case
of excessive vessel pressure. In some cases, such a spontaneous pressure release may occur after the vessel has been removed from the microwave oven.
Hot gases and vapors may be released from the digestion vessel when it is
opened! Always make sure the vent opening on pressure vessels faces away from
both yourself and other individuals!!
Only open the digestion vessel under a fume hood or other exhaust system. Particular care is required when working with hydrofluoric acid (HF). Observe all relevant data sheets and safety instructions!
Never use more than one rupture disc per vessel!
Note:
Renew the vessels after around 10,000 digestions to maintain reliable operating
conditions and to prevent negative influences on your analysis results (e.g. memory effects etc.).
Berghof Products + Instruments GmbH includes its digestion vessels in the warranty coverage. Nevertheless all of the vessels are subject to a certain aging
process, which also depends on the type and frequency of the application. Typically the service life is 10,000 digestion processes or at least 3 years.
Warning !
The unit employs high voltage and generates microwave radiation!
The speedwave four must always be carefully connected to a grounded conductor. Provided the wall outlet used is equipped with a ground connection, the supplied power cord will ensure proper connection. If it is necessary to use an extension cord to connect the system to the power supply, only a three-wire cord with a
ground connection may be employed.
The unit should not be set up near any devices which are sensitive to electromagnetic radiation. If necessary, a warning sign or label indicating “Caution, Microwave Emissions” should be applied or attached to the unit. Should there be any
suspicion or indication of increased levels of microwave radiation, please immediately inform the Service Department at Berghof Products + Instruments GmbH
(Refer to the “Repairs / Customer Service” section for the contact address).
Repair and servicing of the equipment may only be performed by trained
personnel.

Device Description
2.1.
Basic Unit
Device Description
The speedwave four microwave system is designed for pressure digestion
at temperatures up to 230° C (446° F) in continuous use (short term 300 °C /
572 °F) and, depending on the type of vessels employed, pressures up to a max.
of 100 bar (1450 psi).
This is a top loading microwave made of 1.4301 (SS 304) stainless steel and
equipped with a swiveling safety lid, electromechanical locking mechanism and a
circular sample chamber for uniform microwave distribution. The oven has a highly
chemicals resistant PFA coating protecting it from corrosion. Three overtemperature switches and three micro-switches guarantee the necessary operating
safety. The chamber is permanently ventilated by a special fan.
An DIRC thermometer that permits the temperature of the vessel contents to be
quickly determined and regulated is integrated in the microwave oven. The measurement physically determines the temperature radiation emitted by the vessel
contents, that is, the digestion solution. Radiation components emitted by the vessel walls and, in particular, the exterior of the vessel, are completely filtered out.
Optionally the system can be equipped with a contact-free pressure monitoring
system for either individual or for all vessels. This records the internal vessel pressure. If a vessel is approaching its maximum pressure, the system automatically
switches to a pressure-controlled mode for the microwave output.
An unpulsed regulated 2.45 GHz magnetron provides up to 1,450 W of microwave
power. The microwave is controlled by a separate controller with touch-screen. After entering the desired temperature profile, the microwave output is infinitely varied in accordance with the measured sample temperatures. The target and actual
temperatures of all samples are displayed on the screen in real time and saved to
memory.

2.2.
Temperature Monitoring
The speedwave four is equipped with a temperature monitoring system. This system determines the temperature inside the pressure vessels by measuring the direct infrared radiation emitted by the sample. This allows the temperatures of all
samples to be determined. This information is forwarded to the power control module which uses the highest measured temperature to regulate the oven power.
Continuous adjustment of the magnetron output allows the temperature to be regulated on the basis of all vessel contents.
For measurement instrumentation reasons, only temperatures above 50° C (122°F)
can be displayed. Temperatures below 50° C (122°F) are indicated on
the display by “low”.
2.3.
Pressure Monitoring (Option)
Optionally, the speedwave four can be equipped with a pressure monitoring system. To achieve this, the pressure in the vessels is determined by using polarized
light to measure any change in the photoelastic behavior of a glass ring in the vessel lid. This allows the internal pressures of all or of individual vessels to be detected. This information is conveyed to the output control module, which can use
the highest measured pressure to regulate the output. By continuously adjusting
the magnetron output pressure regulation referenced to individual vessels can be
achieved while preventing other over-pressure safety devices (rupture discs) from
being activated.

Berghof Products + Instruments
Pressure Vessels and Rotor Systems
All Berghof pressure vessels are manually operated. A rupture disc placed in the
vessel lid limits the interior pressure of all vessel types to the maximum permissible
value for the individual type. For all vessels except DAP-40+ acid vapors that escape when the rupture disc activates are guided to a collection system integrated
in the rotor. Thereby the vapors are vented or suctioned off through the PFA tube
connected to the swiveling lid.
DAP-40+
DAP-40+ vessels are made entirely of TFM. Aside from chemical resistance to all
mineral acids including hydrofluoric acid, this ensures a high level of mechanical
strength, even at high digestion temperatures.

Device Description
Safety Equipment
Swiveling lid
Warning !
The system is equipped with a solid, PFA-coated, stainless steel housing with a
swiveling safety lid for maximum user safety. The electronic lid-locking mechanism
can only be opened by means of the software control. In addition, 3 interlock
switches are installed which shut the microwave off if the lid is opened by force
during microwave operation.
The unit emits microwave radiation!
Never operate the microwave oven if the swiveling lid or the related lock mechanism have been damaged. Contact your local, authorized dealer or Berghof
Products + Instruments GmbH to obtain the required service (Refer to the
“Repairs / Customer Service” section for contact addresses).
Rupture discs
Warning !
All vessels are equipped with a rupture disc which produces a spontaneous pressure release upwards through the screw-on tube connections in case of excessive
vessel pressure. In some cases, such a spontaneous pressure release may occur
after the vessel has been removed from the microwave oven.
Rupture discs as overpressure protection!
Use only original Berghof rupture discs and protective cover sheets. These can
be obtained from your local, authorized dealer or Berghof Products + Instruments
GmbH (Refer to the “Repairs / Customer Service” section for contact addresses).
Never use more than one rupture disc per vessel!
Gas exhaust
Warning !
All pressure vessels are equipped with a sealed connection to a gas collection system which, in turn, must be connected to an exhaust system via a PFA vent tube.
The PFA tube is connected to the screw-on connection located in the center of the
top of the microwave. Any hot acid vapors released when the rupture disc activates
are safely removed through this PFA vent tube.
Hot acid vapors may be released.
The supplied vent tubes must therefore always be properly connected and attached to an exhaust system.
Make sure the PFA tube is securely attached so that it cannot pop off its connection fitting in case of a percussive pressure burst as occurs when a rupture disc
activates.
Temperature control
The system is equipped with a temperature control of all sample temperatures as
described in the section, “Temperature Monitoring”. An emergency shut-off occurs
in case of a rupture disc break.
Pressure control
Optionally, the system can be equipped with a pressure monitoring system for all
internal vessel pressures as described in the ‘Pressure Control’ section.
Over-temperature
protection
For safety reasons, the microwave automatically switches itself off in case the
magnetron, the microwave oven, or the high voltage transformer overheats.

Installation
DANGER !
The unit employs high voltage and generates microwave radiation!
The speedwave must always be carefully connected to a grounded conductor.
Provided the wall outlet used is equipped with a ground connection, the supplied
power cord will ensure proper connection. If it is necessary to use an
extension cord to connect the system to the power supply, only a three-wire cord
with a ground connection may be employed.
The unit should not be set up near any devices which are sensitive to electromagnetic radiation. If necessary, a warning sign or label indicating “Caution, Microwave Emissions” should be applied or attached to the unit. Should there be
any suspicion or indication of increased levels of microwave radiation, please
immediately inform the Service Department at Berghof Products + Instruments
GmbH (Refer to the “Repairs / Customer Service” section for contact addresses).
Repair and servicing of the equipment may only be performed by trained
personnel.
Positioning
Position the system on the intended work surface. Make sure the vent opening on
the left side of the unit is not covered (at least 15cm (5.9inch) clearance).
A clearance of at least 50 cm (19.7”) that opens towards the front of the unit must
be available above the oven. The work surface must be able to support the weight
of the oven (approx. 65 kg; 143lb) and must have a surface area of approx. 60 x

Method Preparation
4.1.1.
Information Regarding Digestion
The applied microwave energy causes the sample material to heat rapidly. The
speed of this heating process depends on the total volume of liquid in the oven as
well as on the amount of microwave radiation applied (power). The speedwave
four is controlled by continuously adjusting the microwave power. Sample temperature and sample pressure in each vessel are simultaneously acquired in a contactless process during every rotation of the sample turntable, and the microwave
power level is adjusted accordingly. In addition, microwave power is also controlled
on the basis of the number of samples actually present in the turntable. This graduated regulation concept leads to reproducable heating curves and therefore to reproducable results.
Heating the acid mixture results in the creation of vapor pressure. The degree of
this vapor pressure depends greatly on the temperature. All digestion vessels have
a maximum permissible pressure. If this maximum pressure is exceeded, the rupture disc in the pressure vessel activates, providing a rapid pressure release into
the collection vessel.
In addition to the vapor pressure, reaction gases (primarily carbon dioxide generated by samples containing carbon) also produce pressure. This pressure is therefore dependent on the sample amount, the vessel volume, as well as the carbon
content of the sample.
Together with the applied microwave radiation, digestion of organic substances
also releases reaction heat. These types of reactions frequently begin in the temperature range between 130 - 150°C (266 - 302°F). We therefore recommend holding the samples at this temperature for some time (3-5 minutes), in order to allow
this reaction heat to subside somewhat. The temperature should then be increased
to the desired maximum in a second stage in order to obtain optimum digestion
quality.
Caution
Reaching the maximum pressure!
Please note that the reaction pressure is only reached during the course of the reaction, in other words, several minutes after the maximum temperature has been
reached. Therefore, an activation of the rupture discs may be anticipated even after the temperature has reached a constant level.
Optionally the speedwave four can be equipped with pressure monitoring. With
this option the, internal vessel pressure determined and, when the preset maximum pressure is reached, the unit automatically switches to a pressure-controlled
mode. In this mode the microwave output is controlled so that the internal pressure
of the vessel does not exceed the maximum pressure.
Caution
Rupture disc corrosion!
Depending on the acid being employed and the digestion parameters, the aluminum rupture discs are subject to more-or-less extreme wear. Replace the discs
regularly (after approximately ever 20 digestion procedures) to prevent the discs
from rupturing prematurely.

Developing a New Application
Digestion of new sample material, that is, of samples for which you have no previous experience, requires a special, systematic procedure. We recommend the following process when developing such an application:
Check the “Appendix” to determine whether the application list already contains work instructions for the sample material in question or for a similar material then, if necessary, request a copy of the original process instructions from
your local, authorized dealer or from Berghof Products + Instruments GmbH.
Should you not be able to find your sample material, search through the relevant technical literature for a corresponding process instruction. You can also
request assistance from your local, authorized dealer or from Berghof Products
+ Instruments GmbH.
For safety reasons, initially reduce the specified sample amount by 30-50 %,
while still using the specified acid quantity and digesting with the defined temperature program.
Optimize the acid mixture and the temperature profile until you obtain a clear
solution.
In the final step you can gradually increase the sample amount until the
higher pressure causes the rupture disc to activate. The maximum sample
quantity to be used should be approx. 30 % of this amount.
If the pressure control system is installed the maximum sample quantity may
also be estimated from the measured pressures in the digestion vessels.
Note:
When digesting unknown sample materials (e.g., when developing methods) we
recommend digesting only single samples in the speedwave four.
The single sample is automatically positioned directly in front of the sensors and
rotor rotation is stopped. This simplifies continuous temperature and pressure
monitoring for this vessel.

Hardware and Software Operation
Performing a Digestion Procedure
Warning !
Always wear eye protection!
Always wear safety glasses/goggles and protective gloves during work which may
involve contact with chemicals, that is, when working with acids, pressure vessels,
during cleaning, etc.!
DANGER !
Pressure vessels!
Use only digestion vessels and spare parts authorized by Berghof Products +
Instruments GmbH for use with the speedwave. These can be obtained either
from your local dealer or directly from Berghof Products + Instruments GmbH (Refer to the “Repairs / Customer Service” section for contact addresses).
Always wear safety glasses/goggles and protective gloves when working with the
pressure vessels!
Note any changes in the appearance of the pressure vessel which could indicate
possible material fatigue, e.g., deformation of the vessel, difficulty screwing on
lids, etc. even when the vessel is cold and not under pressure. All such vessels
should be immediately returned to Berghof Products + Instruments GmbH for inspection.
Never attempt to use force to open the vessels. Never use tools to open the
vessels!
The pressure vessels are equipped with a rupture disc which produces a spontaneous pressure release upwards through the screw-on tube connections in case
of excessive vessel pressure. In some cases, such a spontaneous pressure release may occur after the vessel has been removed from the microwave oven.
Hot gases and vapors may be released from the digestion vessel when it is
opened! Always make sure the vent opening on pressure vessels faces away
from both yourself and other individuals!!
Only open the digestion vessel under a vent hood or other exhaust system.
Particular care is required when working with hydrofluoric acid (HF). Observe
all relevant data sheets and safety instructions!
Never use more than one rupture disc per vessel!
Note:
Renew the vessels after around 10,000 digestion processes to maintain reliable
operating conditions and to prevent negative influences on your analysis results
(e.g. memory effects etc.).
Berghof Products + Instruments GmbH includes its digestion vessels in the warranty coverage. Nevertheless all of the vessels are subject to a certain aging
process, which also depends on the type and frequency of the application. Typically the service life is 10,000 digestion processes or at least 3 years.
The speedwave four microwave oven can hold up to 24 DAP digestion vessels or
up to 8 DAK-100/4 vessels. Vessel types must not be mixed as this will result in extreme differences in sample heating.
The procedure employed for all vessel types is basically similar. This section therefore first describes the general procedures, while any differences between
the vessel types will be dealt with in detail in the following sections.

Sample amount
Caution
Berghof Products + Instruments
Weigh the sample material into the vessels, then add the acid. The maximum
sample quantity depends on the vessels employed and must be strictly observed
(refer to the “Technical Specifications” section).
Minimum fill amount!
In each pressure vessel, at least approx. 5ml of liquid should be employed so that
the temperature sensor can determine the sample temperature precisely.
The microwave oven requires a certain minimum load of approx. 20 ml of liquid. If
lower volumes of liquid must be used, at least four vessels must be used for each
run in order to achieve the required total load.
If the fluid amount employed is too small, the oven may be damaged during longer
operation! An inadequate liquid load can also result in rotor overheating and, in the
worst case, in rotor damage.
Lid placement
Visually inspect the rupture discs. In case of extensive traces of corrosion or other
visible damage to the rupture discs, they must be replaced for safety reasons.
A bulge in the center of the rupture disc after use is normal and will not affect its
functions.
Make sure the rupture disc is properly seated in the lid, that is, that its edge sits
uniformly in the lid groove.
Press the seal lip on the appropriate molded part to spread the seal ring on the
closure, then place the lid on the lower part of the vessel.
Lock the vessel
Lock the vessel with the coupling cap. Only slight pressure is needed to secure
the rupture disc. Proper vessel seal is ensured by the pressure supported seal lip,
even under maximum interior vessel pressure.
Vessel placement
The rotor should be loaded with the digestion vessels as symmetrically as possible
and the digestion vessels connected to the receptacle. The first vessel must be inserted in the position marked “1” and the rest arranged symmetrically (refer to the
“Attachment”).
Any unused positions on the collection vessel should be sealed with the supplied
blind stoppers or with lock screws in order to ensure the proper operation of the
gas removal.

Close the microwave
Warning !
Hardware and Software Operation
Close the swiveling lid. Insert the vent tube
into the oven from above until it reaches its
stop and make sure that it is properaly connected to an exhaust system.
The vent tube can be connected to an acidresistant suction pump or can be connected
to an existing vent system (e.g., an exhaust
hood).
Close the oven door until the lock engages.
Hot acid vapors may be released.
The supplied vent tubes must therefore always be properly connected and attached to an exhaust system.
Make sure the PFA tube is securely attached so that it cannot pop off its connection fitting in case of a percussive pressure burst as occurs when a rupture disc
activates.
Note:
The desired program must be selected before the microwave oven is started.
Start program
After an appropriate application has been selected or created and the oven has
been filled with the desired number of vessels the digestion program is started with
“Start” in the main menu.
The following input window appears in which the program can again be
modified and a file name can be input. If file names are identical the index is
automatically raised by 1.
Note:
If the program is modified at this stage of operation the modification affects only
the current run, but not the stored application.

Handling the DAP-40+, DAP-30+, DAP-60+, and DAP-100+ Pressure Vessels
The DAP pressure vessels are made up of a TFM pressure vessel, an aluminum
rupture disc, a TFM lid, and a coupling cap . The PP rotor can hold up to 12 DAP60+ vessels.
Weigh the sample material into the vessels. The maximal weighing-in quantity,
which depends on the vessels, must be borne in mind (see 'Technical Data' section).
Weighing-in using TFM To simplify the weighing process and
weighing cups
prevent loss of samples the samples
can be weighed directly into the Berghof
weighing cups made from TFM. These
are placed in the digestion vessel with
the sample and remain there during digestion. After digestion and thorough
rinsing with distilled water they can be
reused.

Rupture disc
DANGER !
Visually inspect the rupture disc. In case of extensive traces of corrosion or other
visible damage to the rupture disc, it must be replaced for safety reasons.
A bulge in the center of the rupture disc
after use is normal and will not affect its
functions. Make sure the rupture disc is
properly seated in the locking lid, that is,
that its edge sits uniformly in the lid
groove.
When using a TFM lid/rupture disk combination of the type offered especially for
digestion processes subject to maximum cleanness requirements, the rupture disk
is not required.
Rupture discs!
Use only digestion vessels and spare parts authorized by Berghof Products +
Instruments GmbH for use with the speedwave. These can be obtained either
from your local dealer or directly from Berghof Products + Instruments GmbH
(Refer to the “Repairs / Customer Service” section for contact addresses).
The pressure vessels are equipped with a rupture disc which produces a spontaneous pressure release upwards through the screw-on tube connections in case

part of the vessel.
Alternatively the sealing lip of the locking
lid can be dilated in the forming station.
The stamp is wound downwards as far as
possible. This station permits a more even
dilation of the sealing lip and is recommended in particular for DAP-100+, DAK17 and DAK-100/4.
Distinct resistance must be felt when the
lid is placed on the pressure vessel. If no
resistance is felt, the seal lip must be
spread as described above.
Close the vessel
After the sample has been weighed in and
the acid has been added, place the seal
lid on vessel and close it hand-tight with
the coupling cap. Only slight pressure is
needed to secure the rupture disc. Proper
vessel seal is ensured by the pressure
supported seal lip, even under maximum

Sample Removal
After the microwave switches off, the vessels must remain in the oven for at least
10 minutes. After this time, all vessels can be removed (disconnect the vent tube
first!) and can be placed under an vent hood or other exhaust system for further
cooling. Acid vapors can leak out of the vessels during the cooling phase. This is
due to the flow behavior of TFM and, generally, does not result in any sample loss
or contamination.
The vessels may only be opened after an adequate cooling period. When the vessels are opened, their internal temperatures should not lie above 100°C (212°F).
The length of the cooling period depends on the heating time and the digestion
temperature. The total cooling time before the vessels are opened should be at
least half the digestion time and, if possible, somewhat more than this.
Warning !
Burn and acid burn hazard!
The digestion vessels must not be removed from the oven for at least 10 minutes
after the end of the digestion program. This will ensure that the samples have
cooled sufficiently to avoid rupture disc breakage caused by jarring during removal.
Always wear safety glasses/goggles and protective gloves when opening vessels!
Always work under an vent hood or other exhaust system!
Never point the gas outlet towards yourself or anyone else. Aggressive gases are

of excessive vessel pressure. In some cases, such a spontaneous pressure release may occur after the vessel has been removed from the microwave oven.
Hot gases and vapors may be released from the digestion vessel when it is
opened! Always make sure the vent opening on pressure vessels faces away from
both yourself and other individuals!!
Only open the digestion vessel under a vent hood or other exhaust system. Particular care is required when working with hydrofluoric acid (HF). Observe all relevant data sheets and safety instructions!
Warning !
Residual pressure in vessels!
Even after cooling, a residual pressure will remain in the vessels!
Always wear safety glasses/goggles and protective gloves when opening vessels!
Always work under an vent hood or other exhaust system!
Never point the gas outlet towards yourself or anyone else. Aggressive gases are
released from here when the vessels are opened or if the rupture disc activates!
Caution
Opening the vessels
If there is still a high residual pressure in the vessel, it will be difficult to unscrew
the lid. If in doubt, allow the vessel to cool for an additional period of time!
If the solution has a high CO2 content, opening the vessel too quickly can cause
the solution to foam up, resulting in sample loss!
To open the vessels, hold onto the coupling cap and slowly
turn the vessel clockwise. Make sure the gas outlet always
faces away from you.
As gases begin to escape from the vessel, wait a moment or
slightly close the vessel by turning it counterclockwise. Continue in this manner and gradually open the vessel.

Do not use perchloric acid.
No organic solvents (alcohols, hydrocarbons, etc.) may be placed in the pressure
vessels or the microwave.
Highly reactive substances which spontaneously react at higher temperatures or
in the presence of oxidizing agents or which may be nitrated and are potentially
explosive may not be digested in the microwave. Examples of such substances
include: explosives (TNT, etc.), perchlorates, ether, pyrophoric substances, etc.
Warning !
Always wear eye protection!
Always wear safety glasses/goggles and protective gloves during work which may
involve contact with chemicals, that is, when working with acids, pressure vessels,
during cleaning, etc.!
3-stage gas scrubber system
Connection for water cooling
Gas exhaust
PFA tube
After connecting the condensation unit to the vent tube, the unit can also be employed to evaporate acids. For this process, the pressure vessels are operated with
a special screw-on cap, without Teflon lid. The vent tube used for evaporating is
equipped with a temperature sensor which must be connected to the socket provided for this purpose on the rear of the unit.
The speedwave four microwave evaporating unit is used to concentrate acids or
sample digestion solutions obtained after digestion procedures employing HNO3,
HCl, HF, and water by means of distillation at ambient pressure. The escaping acid
vapors are condensed and neutralized in a 3-stage, water-cooled gas scrubber
system.
The unit is not suited for concentrating acids or liquids with a boiling point above
200°C (392°F) such as sulfuric and phosphoric acid. For safety reasons (explosion
hazards) the use of perchloric acid and organic solvents is prohibited.
Warning !
EN_Options.doc
Hot acid vapors are generated!
Hot acid vapors are generated during evaporating. Take particular care to ensure
that all connections are secure and do not leak. In particular, the tube connection
between the microwave and the gas scrubber must always be totally sealed.
Secure the tube appropriately to ensure that no acid vapors can escape in the direction of surrounding individuals, even when the screw-on connection is opened.
The microwave system, together with the gas scrubber, must be set up under a
vent hood.

Installation and Commissioning
Ambient conditions
Aside from the requirements cited in the “Ambient Conditions” section of the chapter “Setup and Commissioning”, the operation of the gas scrubber also requires a
coolant water connection (approx. 0.5 liters/min. with an inlet temperature not exceeding 20°C, 68°F). In addition, there is also the need for an increased space of
53 x 27 cm (20.9 x 10.6 inch).
Due to the hot acid vapors generated, the microwave oven and the gas scrubber
system must be set up under a vent hood or other exhaust system. The exhaust
chamber must always remain securely closed during the entire evaporating process.
Gas scrubber

As illustrated in the figures below, add marble granulate to 2 of the gas scrubber
bottles (fill each approx. half-way) while filling the third bottle with NaOH solution
(at least 0.5 mol/l NaOH). Connect the bottles as illustrated in the figures and place
the bottles filled with marble granulate in the cooler. Connect the cooler to a coolant water system with a maximum water temperature of 20°C (68°F). The coolant
water flowrate must be approx. 0.5 liters/min.

Start the microwave
Berghof Products + Instruments
For fortification the magnetron temperature must be set to magT < 20°C in the
temperature program (typical values 5-10°C. The magnetron temperature is recorded continuously and is used to control the distillation process. The terminate
criterion is met if in step 5 the magnetron temperature rises by the specified value
compared to the temperature that arose in step 4.
The power specifications for step 4 and must be selected to be identical to obtain
an expedient terminate criterion. In steps 1-4 the microwave energy is not automatically cut off. The times these steps take depends on the total quantity of fluid
and must therefore be selected in such manner that the temperatures of all samples can stabilize. In step 5 the distillation process is stopped automatically as
soon as the terminate criterion is met. The entire control system is therefore independent of the type of acid.
Example
Start the microwave.
The samples are not evaporated until they are dry. As a rule, a residual volume of
1-2ml remains. In order to concentrate the sample still further, the times in step 1-4
must be increased.
Sample removal
The samples are removed as described in the “Sample Removal” section.
Maintenance
The evaporated acid is condensed and collected in the two gas scrubber bottles.
The acid is neutralized by the marble granulate. The liquid must be poured off as
soon as the gas scrubber bottles are approx. three-quarters full. The granulate can
continue to be used until it has gone completely into solution. The granulate can
neutralize approximately 2 liters of acid. A portion of the acid vapors are also concentrated in the rotor’s collection vessel. This liquid must be removed after every
fuming procedure (refer to the “Cleaning” section).
All TFM components must be cleaned with water and dried before they are again
used.

Oven chamber
The oven should be wiped out with a moist cloth at regular intervals as well as after
any rupture disc activation. All relevant safety measures should be observed in
case of contamination by acids, particularly hydrofluoric acid. Allow the oven to
thoroughly dry before again using it!
Display/Keyboard
Use only a dry cloth to wipe off the display and the keyboard.
Vessels
Since the vessels exhibit practically no memory effects it is generally sufficient to
thoroughly rinse out the vessels with distilled water after each digestion procedure
involving complete digestion.
If discoloration is noted or if carry-over is suspected, the vessels are cleaned by a
blank digestion using acid. In this case, the acid used for the particular application
is filled into the vessel, but no sample is added. After filling, the temperature program for the application in question is started.

DANGER !
The unit employs high voltage and generates microwave radiation!
Any repair and service work may only be performed by properly trained and qualified personnel.
Always unplug the unit from the power supply before beginning any repair or maintenance work.
The high voltage condenser may still carry a charge even after the mains power
plug has been pulled. It must therefore be discharged by bridging the terminals,
e.g., with a well insulated screwdriver. Make sure you are not in contact with any
metal while discharging.
Never alter the settings of the contact switches. However, should it be necessary
to do so, the proper function of the switches must be checked before the unit is
again taken into service. Proper switch function must then be confirmed by measuring the unit’s microwave leakage radiation. This value must lie below the limit
2
value of < 5 mW/cm .

Tips and Tricks
Appendix, Applications
Small sample quantities With the MT or quartz glass inserts small sample quantities <100mg can be digested in a reduced acid volume. This also makes it possible to enhance the detection sensitivity of the entire process.
Multiple samples
per vessel
Higher sample
throughput
Cooling down samples
EN_Appendix_Applications.doc
The MT system makes it possible for 2-3 samples to be digested in a single DAP
100+ or DAK-100/4 digestion vessel at a reduced original sample weight and acid
volume. This enables the sample throughput and productivity of the speedwave
four to be raised.
Cross-contamination from one sample to another is prevented by pre-filling the
same acid mixture into the outer vessel as in the inner vessel. If the acid volume on
the outside is selected so that the liquid level is higher than in the MT vessel, this
also guarantees that the sample is heated up gently.
The sample throughput can also be increased by removing the vessels from the
speedwave four approximately 5 minutes after completion of the last heating stage
and replacing them with new samples. Therefore no time is wasted on cooling
down the samples and idle time in the microwave is restricted to a minimum.
As a rule, the samples cool down in 15-20 min. to the point at which they can be
opened. However, the cooling-down time can reduced to 5-10 min. if the digestion
vessels are placed in a water bath containing cold water.

Dilating sealing lips
Stainless steel
rupture disk
TFM rupture disks
Berghof Products + Instruments
The sealing lips of maximally 6 caps can be dilated fast and simply in the 6-fold dilation tool.
For specific applications Berghof offers stainless steel rupture disks to be used with
the DAP-60+ vessels. Applications are, for example, the digestion of ROHs samples or plastic materials up to 250 mg original sample weight
For specific applications Berghof offers TFM caps with the DAP-60+ and DAP100+
vessels, which are used without additional metallic rupture disks. Potential applications are, for example, digestions for ultra-trace analytics such as those performed
in the semiconductor industry.
When using these TFM caps/rupture disks it must be borne in mind that the rupture
pressure depends on the temperature and the time digestion takes. The reason for
this is the reduced strength of the TFM material at higher temperatures. Metallic
rupture disks do not demonstrate this dependency in the temperature range
< 300°C, which is why it the standard rupture disks used at Berghof are metallic
ones.

Applications
The data listed below are only to be viewed as reference values. Basically, the reaction progression depends on a series of not always predictable factors (distribution of the substances, surface area, catalytic effects of additives), so that spontaneous reactions may occur and result in activation of the rupture disc.
All applications are also available as individual documents. Please contact your
local, authorized dealer or Berghof Products + Instruments GmbH (refer to the
“Repairs / Customer Service” section for contact addresses).
