DTA/DSC


Differential Scanning Calorimetry (DSC) - Differential Thermal Analysis (DTA)


Differential Thermal Analysis (DTA) is a very popular thermal analysis technique it measures endothermic and exothermic transitions as a function of temperature. All Linseis Differential Thermal Analyzers (DTA) comprise the advantages of latest technology, highest resolution and a robust easy to use instrument design.

Certainly the Differential Thermal Analyzer corresponds with all national and international Norms, such as: ASTM C 351, D 3417, D 3418, D 3895, D 4565, E 793, E 794, DIN 51004, DIN 51007, ISO 10837
 

General

The Linseis DTA uses a dynamic measuring principle. It can measure endothermal and exothermal heat flows between the sample and the reference. These heat flows are result of physical or chemical changes of the samples. Very often a DTA is used for purity measurements of mixtures of metals. This is due to the fact that the melting point changes in dependence to differing amounts of impurities.

  • Purity measurements
  • Melting point determination (onset / offset)
  • energy content of explosives
  • stability of explosives (storage)
