Abstract

With some attention to temperature calibration but no other special precautions the temperatures of both solid-solid and melting transitions can be determined to within a few tenths of a Kelvin of absolute values in a range of heat-flux and power-compensation DSC instruments. Materials showing several solid-solid transitions are potentially useful multiple calibrants but require some work to define appropriate thermal treatments that lead to reproducible behaviour.

Zusammenfassung

Unter Beachtung der Temperaturkalibrierung, jedoch ohne jegliche andere Vorkehrungen können in einer Reihe von Wärmefluß- und Leistungskompensations- DSC-Geräten sowohl die Temperaturen von Feststoff-Feststoff-Umwandlungen als auch von Schmelzvorgängen innerhalb einiger Zehntel Kelvin (absolut) bestimmt werden. Substanzen mit mehreren Feststoff-Feststoff-Umwandlungen sind potentiell anwendbare Mehrfach-Kalibrierstoffe, bedürfen jedoch einiger Arbeit zur Festlegung entsprechender thermischer Behandlunge, um ein reproduzierbares Verhalten zu erreichen.
