Recent Development of Heat Flux Type DSC

Recent development of the analyzing method of DSC of heat flux type has been reviewed. In the DSC of heat flux type, sample temperature and heat flux are determined from the time-series data of experimentally available temperatures at the sample stage and furnace. For the determination, the instrumental coefficients such as thermal contact resistance between the sample pan and its stage are required. The following methods are discussed for determining the instrumental coefficients: the methods based on the analytical solutions of the melting of indium, on a standard material with known heat capacity, and on the response of complex heat capacity obtained by T-M DSC. Sample temperature and heat flow under non-steady condition can be evaluated by these methods. The methods also provide reasonable calibration of the dynamic heat capacity of T-M DSC.
