Patent ID: 7306365

Claim:
A differential scanning calorimeter (DSC) system comprising: a sensor within an enclosure comprising: an absolute temperature measurement detector for measuring temperature of a base position on the sensor, a first differential temperature detector for measuring a temperature difference between a sample position and the base position, and a second differential temperature detector for measuring a temperature difference between a reference position and a sample position, means for calibrating the DSC to account for heat leakages between the sample and reference and the enclosure, wherein calibration is performed when the DSC is empty and a first leakage resistance R lc is added in parallel to a measuring thermal resistance of a sample R s and a second leakage resistance R lc is added in parallel to a measuring thermal resistance of a reference R r thereby decreasing an effective resistance of the measuring thermal resistance; operating the DSC; and means for calculating the heat flow to the sample in accordance with the calibration of the DSC.
