12.5 Sample material
Easy to determine are usually samples with the following characteristics:
-
Grainy to powdery, pourable solids
-
Thermally stable materials, emitting the moisture to be determined easily
without other substances evaporating at the same time
-
Liquids that vaporize to leave a dry substance without developing a film
Difficult to determine may be samples that are:
-
Glutinous or sticky
-
Become incrusted easily or tend to form a film
-
Decompose easily under the influence of heat or emit various elements
12.6 Sample size / originally weighted in quantity
Drying times, as well as achievable accuracy, are significantly influenced by sample
distribution. In the course of this arise two opposed requirements:
The lighter the originally weighted in quantity, the easier it is to achieve shorter drying
times.
However, the heavier the originally weighted in quantity, the more accurate a result.
