AN IMPROVED ANALYSIS TECHNIQUE FOR HEAT PULSE MEASUREMENTS

Transient heat pulse techniques allow specific heat (C) and thermal co nductivity (kappa) to be determined from a single measurement. We have developed a new numerical fitting technique to analyse such data, whi ch improves the accuracy of results obtained from heat pulse calorimet ry. In this paper we present two further improvements to this techniqu e which compensate for the finite duration of the heat pulse injected into the sample and any distortion of the temperature response caused by measurement time constants.
