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 ML is a thermogravimetric analyzer which determinesvarious parameters such as moisture, volatiles and ash at user-definedtemperatures and atmospheres in a single analysis.
The TGA Thermostep ML simultaneously analyzes up to 19 samples with sample weights up to 5 g and can be operated at temperatures up to 1000 °C.

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