Eltra Thermogravimetric Analyzer TGA Thermostep

Thermogravimetry is a standard method to analyze organic, inorganic, and synthetic materials. Thermogravimetric 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 that determines various parameters such as moisture, volatile, and ash at user-defined temperatures and atmospheres in a single analysis.

The thermogravimetric 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.

Advantages

• Short heating rates, high-temperature constancy
• Simultaneous measurement of 19 samples
• Sample weight in macro range (multiple grams)
• Crucible covers can be placed and removed during analysis automatically
• Precise, accurate, and reliable determination of moisture, volatile, ash content
• A wide range of materials can be analyzed
• Programmable furnace temperature can be set up to 1000 °c in steps of 1 °c
• Powerful software (multilingual, customized display, the export of results)
• Two thermocouples for precise temperature control
• Balance with 0,0001 g resolution
• Low maintenance
• The robust design allows usage in production control and laboratory
