Thermogravimetry is a standard method to analyze organic, inorganic and synthetic materials. Thermogavimetric analysis in general means the measurement of the weight loss during a user-defined temperature or heating process.
ELTRA’s TGA Thermostep is a thermogravimetric analyzer which determines various parameters such as moisture, volatiles and ash at user-defined temperatures and atmospheres in a single analysis. The thermogravimetrics analyzer TGA Thermostep simultaneously analyzes up to 19 samples with sample weights up to 5 g and can be operated at temperatures up to 1000 °C.
A special feature of the TGA Thermostep is the management of crucible covers. The thermogravimetric analyzer can place and remove the covers of the crucibles during analysis. This feature allows for example the precise determination of volatile content in coal and coke.

Operation of the thermogravimetric analyzer TGA Thermostep is simple and convenient. The measurement process has to be defined once regarding the used temperatures, atmospheres and heating ranges. To start the thermogravimetric analysis, a predefined process simply has to be chosen in the software and the sample has to be weighed into the crucible. All further steps are processed automatically. All data processing, control of the measurement process and calculating of the result is done by an external PC with Windows®-based software. Thermogravimetric analysis of moisture, volatile and ash content requires about 4 hours.
