Equipment Description:

Thermogravimetry is a standard method of analysis of organic, inorganic and synthetic samples in which the variation in the weight of a sample is measured after it has been subjected to a certain temperature.

ELTRA's TGA Thermostep is a thermogravimetric analyzer that can determine different parameters such as moisture content, volatile matter and ash in a single analysis cycle. The temperature and gas in the oven atmosphere are user-defined.

The TGA Thermostep can analyze up to 19 samples weighing 5 g in a single analysis cycle and reaches a maximum temperature of 1000 ° C.

A special feature of the TGA Thermostep is the system for placing and removing the lids of the crucibles during the analysis. This function allows you to accurately determine the volatile matter content in coal and coke.
