2.2
Selection of Temperature
The temperatures given in the materials table are proposals, which might not fit always for
each member of a group of materials. Generally a temperature is chosen which is as high as
possible to accelerate the evaporation of water but low enough to avoid thermal decomposing.
Usually the melting of the sample should be avoided to allow easier cleaning of the sample
tray. If you are not sure which temperature is appropriate, try lower temperatures first. In
some cases the melting of the sample might be necessary (e.g. to investigate the behavior of
compound fillers), then a (dry!) aluminum film can be inserted into the tray before the
measurement.
If the heating temperature and the density of a single sample deviates from the usual
characteristic, it can be added in the input mask 2 without changing the material table.
2.3
Selection of Sample Weight
The selection of the sample weight has to consider the expected moisture content: Samples
with a high moisture content have to be smaller than samples with a low moisture content. A
water content of more than 25 mg per sample has to be avoided. The software stops a test
when a water content of 25 mg is exceeded.
After pressing in input mask 2 the following window opens:
(A) Selection field for the expected water content of the sample
(B) Display field for recommended sample weight
(C) Pressing the button starts the calculation of the sample quantity
(D) Pressing the button closes the application
