ABSTRACT
Reports on the development of a new method that fits the whole temperature response of a heat-pulse calorimeter for heat capacity. Analyzation of the thermal response of a heat-pulse calorimeter on a model that was used by the relaxation method to derive some useful relations and further utilize the numeric method of the general linear least squares to determine the heat capacity of a sample; Accuracy of the proposed method which was verified by determining the heat capacity of a 0.249 76 g copper sample; Comparison of the result with the literature; Indication that the proposed method is capable of measuring heat capacity regardless if the sample is adiabatically or nonadiabatically isolated; Details of the employed calorimetric system.

    An automated adiabatic calorimeter with an internal volume of 5 cm3, operable over the temperature range from 30 to 380 K is described. One of the main advantages of this calorimeter over others in use is the much abbreviated down time during sample changes, due to interchangeable sample vessels...

    We introduce a scanning calorimeter for use with a single solid or liquid sample with a volume down to a few nanoliters. Its use is demonstrated with the melting of 52 nL of indium, using heating rates from 100 to 1000 K/s. The heat of fusion was measured to within 5% of the bulk value, and the...

    A high resolution nonadiabatic method for measuring the heat capacity (C[sub P]) of bulk samples of condensable gases in the range of 7.5-70 K is described. In this method C[sub P] is evaluated by directly comparing the heating and cooling rates of the sample temperature for two algebraically...
