The TGA Thermostep elemental analyser

World Coal,

The TGA Thermostep from Eltra, a leading manufacturer of elemental analysers, is a thermogravimetric analyser that determines various parameters, such as moisture, volatiles and ash content in one analysis.

Elemental analysers for the mining industry

The user defines the temperature profiles and atmospheres according to their requirements. The TGA Thermostep can analyse up to 19 samples with a maximum weight of 5 g each, reaching temperatures of up to 1000 °C. To determine volatile components in a sample reliably and in accordance with the ASTM standard, the crucible lids can be automatically placed and lifted during analysis following a user-defined programme.

Operating the Thermostep is simple and safe. Parameters such as heating rate, hold time and atmosphere, etc., only need to be defined once for the first analysis and can then be conveniently saved and called up for subsequent measurements. The user defines the temperatures and related hold times until the desired constant weight is obtained and/or a time limit is reached.

Eltra also offers thermogravimetric analysers with integrated automatic sample loading, which substantially increase the sample throughput. The range of application areas for the TGA Thermostep includes food, environment, plastics, mining and metal processing.
