ABSTRACT
The linear drop and exponential recovery shape of these transformations also appear in power-compensated DSC traces, but for different reasons. The temperature measuring device (RTD) measures its own temperature, which is influenced by all substances in the chamber, the housing, the sample crucible, as well as the melting sample. The device adds power to the sample side as needed to compensate for the cooling effect on the chamber due to sample melting. This energy requirement increases linearly since the setpoint sample temperature increases linearly. When melting is over, the need for extra heat· flow to the sample chamber side drops exponentially as the chamber temperature quickly catches up to the setpoint.
