Abstract
A sensor for a heat flux differential scanning calorimeter in which one absolute temperature measurement and two differential temperature measurements are used. The sensor is calibrated and used based on a four-term model heat flow equation. The calibration is carried out in two experiments which are used to calculate the sensor thermal resistance for the sample and reference positions, respectively, and the sensor heat capacity for the sample and reference positions, respectively. Differential scanning calorimeters using this sensor exhibit improved resolution, improved baseline performance and improved dynamic response.
