Journal of thermal analysis Aims and scope Submit manuscript

Abstract

It is shown that it should be possible to construct a single-run heat conduction type DSC that records heat capacity directly, eliminating the present need for three separate runs. A simplified mathematical derivation of the needed computation is given and some suggestions about improved DSC construction are presented.

Zusammenfassung

Es wird gezeigt, daß es möglich sein müßte, ein single-run DSC vom Wärmeleittyp zu konstruieren, mit dessen Hilfe man anstelle der bisherigen drei separaten Durchgänge die Wärmekapazität direkt registrieren kann. Es werden für die notwendigen Berechnungen eine vereinfachte mathematische Ableitung und für den Bau des verbesserten DSC einige Anregungen gegeben.

Резюме

Показано, что предста вляется возможным построить дифференц иальный сканирующий калорим етр с тепловым потоко п, позволяющий единств енным измерением непосредственно опр еделять теплоемкост ь, исключая тем самым три отдельн ые стадии измерения, как это тре бовалось до сих пор. Пр иведено упрощенное математи ческое дифференциро вание требуемых вычислени й и представлены некоторые предложен ия по улучшению конструкции ДСК.
