Development and applications of a low-temperature differential thermal analyzer (77 < T, K < 330)

  • P. Knauth
  • R. Sabbah


A differential thermal analyzer for the temperature range 77 to 330 K is described and some applications, determination of the impurity content, the triple point temperature and the enthalpy of fusion of a substance, are given. The temperature and energy calibration of the apparatus are done with diphenyloxide, hexafluorobenzene and 1,3-difluorobenzene. The energy calibration coefficient can be expressed as a linear relation ofT3.n-Heptane, cyclohexane and 1,2-dichloroethane are investigated.

Es wird eine DTA-Apparatur für den Temperaturbereich 77-330 K beschrieben und einige Anwendungen gegeben, z. B. die Bestimmung des Verschmutzungsgrades, des Tripelpunktes oder der Schmelzwärme einer Substanz. Die Kalibrierung der Apparatur auf Temperatur und Energie erfolgte mit Diphenyloxid, Hexafluorbenzol und 1,3-Difluorbenzol. Der Kalibrationskoeffizient für die Energie kann als eine lineare Funktion vonT3 beschrieben werden.n-Heptan, Cyclohexan und 1,2-Dichlorethan wurden untersucht.
