 Fill the decomposition vessel using oxygen sta-
tion C 248 (see section 4.10).
 Slide the ignition adaptor onto the decompo-
sition vessel.
For information on how to operate the decompo-
sition vessel, please see the operating instructions
provided.
6.2 Preparing the decomposition vessel
Prepare the decomposition vessel as follows:
 Unscrew the union nut and remove the cover
using the handle.
 Attach a cotton thread to the centre of the
ignition wire using a loop.
 Weigh out the substance directly into the
crucible with an accuracy of 0.1 mg. Note the
weight or enter directly into the calorimeter. (See
section 6.3 "Preparing the measurement").
 Insert the crucible into the crucible holder.
If necessary put some distilled water or a solution
into the decomposition vessel.
See section 5.3 "Information about the samp-
le" and section 1 "Safety precautions”.
 Using tweezers, align the cotton thread so that
it hangs inside the crucible and is immersed in the
sample. This will ensure that the burning thread
ignites the sample during the ignition process.
 Attention! Place the cover onto the lower
section and push down until it presses against the
stop piece in the lower section. Place the union
nut onto the lower section and tighten by hand.
