1Basic information
1.1 User manual notes
The user manual describes the TOPwave microwave digestion system.
The TOPwave is intended for operation by qualified specialist personnel observing this
user manual.
The user manual informs about the design and function of the TOPwave and provides
the necessary know-how for the safe handling of the device and its components to per-
sonnel familiar with analysis. The user manual further includes notes on the mainte-
nance and service of the equipment and potential causes and remedies of any faults.
Instructions for actions which occur in chronological order are numbered and combined
in action units.
Warnings are indicated by a warning triangle and signal word. The type, source and
consequences of the danger are stated together with notes on preventing the danger.
The meaning of the signal words used is explained in section "Safety instructions" p. 8.
The elements of the control and analysis program are indicated as follows:
Program terms are identified with SMALL CAPS (e.g., Menu FILE).
Buttons are shown by square brackets (e.g., [OK])
Menu items are separated by arrows (e.g.FILE OPEN)
The user manual uses the following symbols and signal words to indicate hazards or in-
structions. The warnings are always placed before an action.

1.2 Intended Use
WARNING
The unit is
not designed for extraction and metabolization procedures employing orga-
nic solvents.
WARNING
Since sample composition is generally not precisely defined, a certain residual risk exists
when performing pressure digestion processes. Careful working prac
tices 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 stric
tly 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 TOPwave microwave digestion system has been designed to perform chemical di-
gestion procedures under extreme pressure and temperature conditions in chemical la-
boratories. 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 per-
meable with regard to microwaves. The digestion solutions are directly heated through
the absorption of the microwave radiation by the polar digestion reagent, which gene-
rally 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 ini-
tial 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 TOPwave 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 da-
mage 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 inse-
rts 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, except PM 40.
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 TOPwave microwave digestion system.

TOPwave 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 sys-
tem to the power supply, o
nly 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 appli
ed or attached to the unit. Should there be any suspicion or indication of
increased levels of microwave radiation, please immediately inform the Service Depart-
ment at Analytik Jena AG.
The housing cover may only be removed by authorized trained personnel!
The unit must be disconnected from the mains power supply.
Renew vessels!
WARNING
Renew the vessels after around 10,000 digestions to maintain reliable operating condi-
tions and to prevent negative influences on your analysis results
(e.g. memory effects
etc.).
Analytik Jena 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 servi
ce life is 10,000 digestion processes
or at least 3 years.
2.5 Safety Equipment / Emergency
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.
WARNING
The unit emits microwave radiation!
Never operat
e the microwave oven if the swiveling lid or
the related lock mechanism has
been damaged. Contact your local, authorized dealer or Analytik Jena AG to obtain the

All vessels are equipped with a rupture disc which produces a spontaneous pressure re-
lease upwards through the screw-on tube connections in case of excessive vessel pres-
sure. In some cases, such a spontaneous pressure release may occur after the vessel has
been removed from the microwave oven.
WARNING
Ru

Use only original Analytik Jena rupture discs and protective cover sheets. These can be
obtained from your local, authorized dealer or Analytik Jena.
Never use more than one rupture disc per vessel!
Only use ru
pture discs which are designed for the respective vessel!
All pressure vessels are equipped with a sealed connection to a gas collection system
which (without PM 40), 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.
WARNING
Hot acid vapors may be released!
The sup
plied 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 fit-
ting in case of a percussive pressure burst as occurs when a
rupture disc activates.
The system is equipped with a temperature control of all sample temperatures.
An emergency shut-off occurs in case of a rupture disc break.
Optionally, the system can be equipped with a pressure monitoring system for one or all
vessels.
For safety reasons, the microwave automatically switches itself off in case the magnet-
ron, the microwave oven, or the high voltage transformer overheats
In the following situations, the unit must be disconnected from the mains power supply
and be locked out to prevent accidental use:
if the unit evidences visible signs of damage
if unit parts or components are found to be loose
if the unit fails to operate
if the unit is to be stored for extended periods of time under unfavorable conditions

4Device Description
4.1 Basic Unit
The TOPwave microwave system is designed for pressure digestion
at temperatures up to 230 °C (446 ° F) in continuous use 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 over-temperature switches and three
micro-switches guarantee the necessary operating safety. The chamber is permanently
ventilated by a special fan.
A RTM thermometer that permits the temperature of the vessel contents to be quickly
determined and regulated is integrated in the microwave oven. The measurement physi-
cally 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, optical 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. The microwave is
controlled by a separate controller with touch-screen. After entering the desired tempe-
rature 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.

4.2 Temperature Control
The TOPwave is equipped with a temperature monitoring system. This system deter-
mines the temperature inside the pressure vessels by measuring the direct infrared radi-
ation emitted by the sample. This allows the temperatures of all samples to be deter-
mined. This information is forwarded to the power control module which uses the hig-
hest measured temperature to regulate the oven power. Continuous adjustment of the
magnetron output allows the temperature regulation on the base 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”.
1 Infrared filter
2 Measurement sensor
4.3 Pressure Monitoring (Option)
Optionally, TOPwave 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 inter-
nal 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 refe-
renced to individual vessels can be achieved while preventing other over-pressure safety
devices (rupture discs) from being activated.

NOTICE
The safety of the vessels is guaranteed by the rupture discs. Pressure and temperature
measur
ement serve to control the digestion process, but have no primary safety func-
tion.
4.4 Pressure Vessels and Rotor System
All vessels can be opened and closed tool-free. A rupture disc placed in the vessel lid li-
mits the interior pressure of all vessel types to the maximum permissible value for the
individual type. For all vessels, except PM 40, acid vapors that escape when the rupture
disc activates are guided to a collection system integrated in the rotor. Thereby the va-
pors are vented or suctioned off through the PFA tube connected to the swiveling lid.
PM 40 vessels are made entirely of TFM -PTFE. Aside from chemical resistance to all
mineral acids including hydrofluoric acid, this ensures a high level of mechanical
strength, even at high digestion temperatures.
