Operating Variables and Sample Handling
The DSC 4000, DSC 6000, Pyris 6 DSC and the Jade DSC measure differential temperature
and report the heat flow to the sample as it is heated, cooled, or held isothermally. The
following topics discuss the materials and techniques used to obtain data with a DSC 4000,
DSC 6000, Pyris 6 DSC or a Jade DSC.
Temperature Range
The temperature range for your analysis depends on the sample and the type of experiment
you are performing. The Pyris 6 DSC can be used to analyze samples from a temperature of
–120 °C to 200 °C when used with cold nitrogen gas or from ambient to 445 °C. The
DSC 4000 can be used to analyze samples from –65 °C to 445 °C with the Intracooler with
the PCD. The DSC 6000 and Jade DSC can be used to analyze samples from a temperature
of –170 °C to 300 °C when used with liquid nitrogen or from –65 °C to 445 °C with the
Intracooler (P/N N5374098/N5374099).
Scanning Rate
The DSC 4000, DSC 6000, Pyris 6 DSC and the Jade DSC allow heating rates of 0.1 to
100 °C/min in steps of 0.1 °C/min. Proper selection of heating rate will increase efficiency of
your analysis at the desired sensitivity. Generally, slower heating rates improve the peak
resolution while faster heating rates improve the apparent sensitivity. Heating rates greater
than 40 °C/min are generally used for rapidly heating or cooling the analyzer to the
beginning temperature of the next segment or to selected isothermal temperatures in the
temperature program. Typical experimental heating rates range from 5 to 20 °C/min. Slower
rates can be used for liquid crystals and purity analyses. Refer to the Help for other topics on
