Deviations:

no

Principles of method if other than guideline:

The test item sample and reference material are both maintained at the temperature
predetermined by the program even during a thermal event in the sample. The amount of
energy which has to be supplied to the sample to maintain zero temperature differential
between the test item sample and the reference material is the experimental parameter
displayed as the ordinate of the thermal analysis curve. The rate of energy absorption by the
sample is proportional to the specific heat of the sample.
Any transition accompanied by a change in specific heat produces a discontinuity in
the power signal.
Boiling of the test item will be characterized by an endothermic enthalpy change that
gives a peak whose area is proportional to the total enthalpy change.
The boiling temperature depends on the atmospheric pressure so boiling
temperature will be corrected if necessary.

GLP compliance:

yes (incl. QA statement)

Type of method:

differential scanning calorimetry
