Abstract

Through two simple and well-known examples, there are shown the limits and defects of DTA method of investigation in comparison of results obtained recently with true and moderns calorimeters.

Today we must not confuse the true calorimetrical results with the DSC results (or DTA masked results) which give only an estimated value of temperature and heat about the phenomenon.

Zusammenfassung

Anhand zweier einfacher und gutbekannter Beispiele werden Grenzen und Fehler der Untersuchungsmethode DTA im Vergleich zu Ergebnissen gezeigt, die mit echten und modernen Kalorimetern erhalten wurden.

Man darf die echten kalorimetrischen Ergebnisse nicht mit DSC- (oder DTA-) Resultaten durch-einenderbringen, die ihrerseits bezüglich der fraglichen Erscheinung nur einen geschätzten Temperatur- und Wärmewert liefern.
