<p>The temperature of a heat reservoir (1) is varied according to a linear function which is AC modulated. At this time, the temperature difference between two points (9, 11) located in a heat flow path going from the heat reservoir to an unknown sample (8) is measured. Also, the temperature difference between two points (10, 12) located in a heat flow path going from the heat reservoir to a reference sample (7) is measured. These two pairs of points are arranged symmetrically. Then, the resulting signals are demodulated, and each signal is divided into an AC component and a low-frequency component. Using these signals, the DSC signal is separated into a heat capacity component and a latent heat component. <IMAGE></p> |
