The Remote Ignition Unit AOD 1.2 must only be opened by an
authorised serviceworkshop. If servicing is required, we recom-
mend that you take advantage of our customerservice facilities.
Further, please make yourself familiar with the relevant safety
and accident preven-tion regulations.
Parts carryingelectric voltage:
IKA®accepts no liability for damage or costs that arise due to
accidents,misuse of the unit, or unauthorised changes, repairs or
modifications.
The system has the following important features:
• In an atmosphere of pure oxygen, core temperatures of over
1300°C, at pres-sures up to 195 bar, can be reached in the
crucible.
• The decomposition vessel is made from a highly halogen-re-
sistant special alloy.For quantitative determination of fluorine,
chlorine, bromine, iodine and sulphur,the inner surfaces and
parts are catalytically activated.
• The gases generated during combustion can be dissolved in a
special absorp-tion solution, which is added to the decompo-
sition vessel.
• Manual ignition of the sample using the remote ignition unit.
• Guard AOD 1.3 for safe operation (optional).
• The detection method for dissolved ions can be selected by
the user. Ion chro-matography, detection with ion-selective
electrodes, or titration are suggested methods. The following
publications use these methods:
– GIT 4/96: Determination of element specific halide- and sul-
fur-contents inorganic matrices.
– GIT 7/96: New aspects within calorimetry.
– GIT 11/96: Determination of calorific values with simultane-
ous halogen andsulfur decomposition.
These publications are available from IKA®.
1.5 Warranty
In accordance with IKA®warranty conditions, the warranty pe-
riod is 24 months. For claims under the warranty please contact
your local dealer. You may also send the machine direct to our
factory, enclosing the delivery invoice and giving reasons for the
claim. You will be liable for freight costs.
The warranty does not cover worn out parts, nor does it apply
to faults resulting from improper use, insufficient care or mainte-
nance not carried out in accordance with the instructions in this
operating manual.
Safety instructions
Read the operating instructions in full before starting up
and follow the safety instructions.
Keep the operating instructions in a place where they can be
accessed by everyone.
Ensure that only trained staff work with the appliance.
Follow the safety instructions, guidelines, occupational health
and safety and accident prevention regulations.
Intended purpose:
The decomposition system AOD 1 is designed for the test sample
decomposition of halogenated and sulphurous substances. The
system must only be used for this purpose in conjunction with
the original IKA®reaction vessel AOD 1.1. For detailed informa-
tion, see the operating manual for the reaction vessel.
Operating requirements:
The operator of this equipment must ensure safe operation of
the decomposition vessel AOD 1.1 by installing a suitable safety
device (e.g. safety guard AOD 1.3).
The maximum energy input in the decompositi-
on vessel must not exceed 30000 J and the sam-
ple mass should therefore be chosen accordingly.
The maximum permitted operating pressure is
195 bar (19,5 MPa); do not exceed this pres-
sure. The maximum permitted operating temperature is
50 °C; do not exceed this temperature.
Do not overfill the decomposition vessel with the sample sub-
stance. Fill the decomposition vessel with oxygen at a pressure
not exceeding the permitted maximum of 40 bar (4 MPa).
Check the pressure on the pressure reducer. Before the start of
every combustion cycle, perform a seal test (following the inst-
ructions in the decomposition vessel operating manual).
When using protective device AOD 1.3, a minimum distance
of 2metres should be observed. Should a decomposition vessel
burst, the device will not protect against damage to hearing.
Always wear hearing protection in order to avoid damage to
the ears.
Explosivstoffe:
Some substances tend to combust in an explosive manner due
to peroxide build-up. This can cause the decomposition vessel
to burst.
The decomposition vessel AOD 1.1 must not be used for
the testing of explosive samples.
Hinweise zur Probe:
Substances whose combustion behaviour is unknown must
be tested prior to com-bustion in the decomposition vessel
AOD 1.1 to establish there combustion behaviour (explosi-
on hazard). When you burn an unknown sample, maintain a
safe distance from the decomposition vessel. With the guard
AOD 1.3 fitted, the minimumsafe distance is 2 metres.Benzoic
acid must only be burnt in its compressed form. Combustible
dusts andpowders must be pressed before testing. Explosion
hazard: over-dried dusts and powders (e.g. wood shavings and
sawdust, hay and straw) burn in an explosive manner. Wet these
substances before testing. Keep slightly flammable fluids with
alow vapour pressure (tetramethyl-dihydrogendisiloxan) away
from cotton yarn; prevent all contact between these two sub-
stances.
