method and arrangement for differential hybrid densitometers - calorimetry

摘要

The method involves changing the temperature in a thermostat having measuring chambers for a sample to be examined and a reference sample, according to a start-target temperature cycle. The temperature difference between the samples is recorded as a function of temperature or time. At the same time, the characteristic frequencies of the chambers are stimulated using oscillation devices. The oscillation periods are determined and displayed. An Independent claim is included for a device for carrying out the method.
