Differential Thermal Analysis

Differential thermal analysis (DTA) is a widely used method for analyzing materials. DTA utilizes the fact of a characteristic energy conversion during the phase transition for qualitative and quantitative analysis. The measurement is based on a comparison of the sample temperatures with a reference. The devices are used to characterize pharmaceuticals, food, chemicals and inorganic substances. Typically effects like glass conversions, crystallization, melting and sublimation can be measured.

The modular concept of our DSC and DTA systems enables us to cover a temperature range from -150°C to 2400°C using various furnaces, measuring systems and crucibles.

Due to the vacuum-tight design, measurements of the enthalpy under the cleanest atmospheres and under a vacuum of up to 10E^-5 mbar are possible. In addition, our systems can be equipped with a mass spectrometer or FTIR to obtain further information.

All DTA devices operate in accordance with the following national and international standards ASTM C 351, D 3417, D 3418, D 3895, D 4565, E 793, E 794, DIN 51004, DIN 51007, ISO 10837.
