Abstract
The construction of a high pressure DSC measuring head for the Perkin-Elmer DSC-7 is presented. The DSC cell is developed to work in a range of temperature from 290 to 570 K at a maximum pressure of 500 MPa using different silicon oils as pressure medium. This calorimeter works with the common heating rates from 0,1 K min to 30 K min . The noise of the base line is about 50–100 μW depending on the pressure in question. The repeatability of the base line amounts to 2–3 mW. The new high pressure cell is especially useful for DSC measurements in polymer science preliminary results are presented.
