Sample Material; Sample Size / Originally Weighted In Quantity - KERN DLT-N Operating Manual

15.5 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

15.6 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.
