1.1 General

SCROLL TO TOP

1.1.1 Principle

The principle of differential scanning calorimetry [1] is based on the measurement of variations in the thermal energy supplied to the sample to be analyzed, compared with that supplied to an inert body called the control, in order to impose a controlled temperature program.

In differential thermal analysis (DTA), the measured variable is the temperature gradient between sample and control. In this...
