摘要: The present invention comprises a calorimeter apparatus having a very low thermal mass ratio of test cell to test sample so as to minimize heat sink effects on the test sample during a chemical reaction. The heater control algorithm of the present invention comprises a calibration stage in which the heater is tuned to the particular test conditions at hand, and a test stage in which the heater may control the sample in a ramping mode and in an adiabatic mode. Because the sample may be tested in an adiabatic mode, greatly improved sensitivity in detection of reaction onset may be achieved, and measured data is truly adiabatic and need not be adjusted for analysis. The present invention further comprises a calorimeter apparatus having a foam detector for detecting the presence of foam in the test sample.
