Differential scanning calorimeter
The two most common types of differential scanning calorimeter, are heat flux DSC, which operates by keeping the heat supply to the system as constant and power-compensated DSC, which works by maintaining the power supplied to the calorimeter as constant. In general, a DSC calculates heat changes by measuring the temperature difference between the sample and reference holder. The typical design of the heat flux DSC can be seen from  Figure 1. It contains the sample holder, where the material of interest is placed, and the reference holder, which is generally kept empty. Both of these are placed on a support, which is in good contact with the walls of calorimeter. The heating resistor is attached to the boundary walls that enables one to obtain a furnace generating and keeping the required heat amount inside the enclosure. The thermocouple connected to both sample and reference holder is a measuring device that gives the temperature to be used in the analysis. Heat supplied by the heating resistor flows further into the sample and the reference materials chambers.
