Abstract

The correctness of a kinetic experiment is an essential condition for obtaining reliable results in kinetic investigations. Methods for provision and testing of thermo-physical and concentration correctness are discussed in the present article. Problems connected with the non-isothermal mode of an actual thermoanalytical experiment caused both by programming and by heat release in the sample are considered. Application analysis of the combined partial-linear heating laws in kinetic investigations is given in relation to the heat flux calorimeters ‘SETARAM’.

Zusammenfassung

Die Korrektheit eines kinetischen Versuches ist eine wesentliche Voraussetzung, um in kinetischen Untersuchungen zuverlässige Ergebnisse zu erhalten. In diesem Artikel werden Methoden zur Bestimmung und zum Testen der Richtigkeit hinsichtlich der Thermophysikund und der Konzentrationen beschrieben. Dabei werden Überlegungen zu Problemen bei nichtisothermen thermoanalytischen Versuchen angestellt, die sowohl durch Programmierung als auch durch Wärmefreisetzung verursacht werden. In Bezug auf das Wärmeflußkalorimeter “SETARAM” wird eine Analyse der Anwendung des Gesetzes der kombinierten partial-linearen Erhitzung in kinetischen Untersuchungen beschrieben.
