最近の熱流束DSCの発展

Recent Development of Heat Flux Type DSC

熱流束DSCの測定・解析法に関する近年の発展について解説する。熱流束DSCでは,試料台温度,炉温度など実測可能な時系列データから,試料温度・熱流束を決定する。その際必要となる装置係数の決定方法として,インジウム融解に対する解析解に基づく方法,既知の熱容量をもつ標準試料を用いる方法,温度変調法を利用する方法について解説する。これらの手法により非定常状態での試料温度・熱流束を決定できる。また,温度変調DSCで得られる動的複素熱容量の較正も行える。
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.
