Modulating differential scanning calorimeter

This is a later version of DSC in which the a small oscillation is imposed upon the otherwise linear heating rate.

This has a number of advantages. It increases sensitivity, allowing slow scans. It facilitates the direct measurement of the heat capacity in one scan. It also permits the simultaneous measurement of heat effects that are reversible and not reversible at the timescale of the oscillation. (reversing and non-reversing heat flow resp.)
