The temperature of a heat reservoir is varied according to a linear function which is AC modulated. At the same time, a temperature difference between two points located in a heat flow path from the heat reservoir to an unknown sample is measured. The temperature difference between two points located in a heat flow path from the heat reservoir to a reference sample is also measured. These two pairs of points are arranged symmetrically. The resulting DSC (differential scanning calorimeter) signals are demodulated and each signal is divided into an AC component signal and a low-frequency component signal. Using these signals the, DSC signal is separated into a heat capacity component and a …

Why it's free to use
- Filed March 25, 1994 and granted November 23, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended March 25, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by March 25, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
