11 Moisture analysis

11.1 Define the drying method

The optimum drying parameters (drying temperature and drying period) depend on
the type and size of the sample and the required accuracy of the measuring result.
In most cases it is only possible to find out the sample-specific parameters by trial
and error.
or
Guidance is available in form of existing standards, in-house directives or
recommendations.
For examples please also refer to our application manual which you can download
from our KERN- Homepage (www.kern-sohn.com).
The following parameters can be set for defining a method:
 Drying temperature, see chap. 11.1.1.
 Switch-off criterion, see chap. 11.1.2
 Heating profile, see chap. 10.1.1
 Result display, see chap. 11.4

11.1.1 Setting the drying temperature

The drying temperature influences considerably the measuring time. It must be
selected in a way that the sample neither does decay nor changes its chemical
structure. A too deep drying temperature lengthens innecessarily the drying time.
