ELTRA TGA analyzers are an ideal alternative to standard laboratory ovens and muffle furnaces for thermogravimetric analysis.
The TGA Thermostep ML processes up to 19 different samples, typically weighing between 500 mg and 5 g, in one analysis cycle. The surrounding atmosphere and temperature of up to 1,000 °C within the heating chamber can be freely defined by the user during analysis to create a standard operating procedure. The crucible lids, covering of the samples, can be added or removed at each stage of the analysis, thus allowing for safe and ASTM compliant determination of volatiles in coal samples.
Typical sample materials: Coal, coke, secondary fuels, gypsum, flour, plastics, ceramics and many more.
