Tips for Sample Preparation for DSC Measurements

Careful sample preparation ensures reproducible and reliable DSC results.

The following factors can influence a DSC measurement:

Pan material:

 

Lids:

 

Sample:

  • For DSC measurements on compact samples, a single sample specimen is ideal.
  • In order to achieve good heat transfer between the sample and the pan bottom, the sample should have one surface with an area as smooth as possible which allows it to lie flat at the bottom of the pan. It is particularly easy to cut polymer granulates, for example, with the SampleCutter.
  • Overall, the sample should not be too high, in order to ensure that the bottom does not become deformed when the pan is pressed. For powders, it has been determined to be a good idea to compact these when possible.
