THERMOGRAVIMETRIC ANALYZER (TGA)

Almost all Linseis instruments for thermogravimetric analysis (TGA) are top loading, and come with user-friendly design with a highly sensitive measurement system. The specially designed furnaces allow fast heating and cooling rates as well as a highly precise temperature control in a temperature range from -150°C up to 2400°C.

Thermogravimetric analysis determines the mass change of a sample or material over time as the temperature changes, during heating or cooling. The result obtained is also referred to a mass change or weight change versus either temperature or time, and is usually given in micrograms [μg]. The determination of the mass change is performed with a thermobalance in the TGA instrument.

The thermobalance consists of the oven with precise temperature control, the highly accurate electrical balance, with supply lines of required gases and data processing units for the measured value processing.

The TGA measurement is useful for study of physical properties, such as phase transitions, absorption, adsorption and desorption; as well as chemical reactions such as chemisorptions, thermal decomposition, and solid-gas reactions due to oxidation or reduction.
