Abstract
A method for calculating sample heat flow in a differential scanning calorimeter. A preferred embodiment of the invention calculates the heat flow to the sample while accounting for the effect of heat storage in the sample pans and the difference in heating rate between sample and reference. Accounting for heat flow associated with the pans and the difference between sample and reference heating rates gives a more accurate sample heat flow measurement and improves resolution, which is the ability to separate closely spaced thermal events in the heat flow result.
