Thermogravimetric analysis (TGA)

In TGA, the sample is heated at a controlled rate or kept at a controlled temperature, while its mass is weighed with an extremely precise scale. Thermogravimetric analysis may give information about phase transitions, absorption, adsorption, desorption, chemisorption, thermal decomposition, and solid-gas reactions. It may also be used as a characterization method and for compositional analysis. With this measurement, you will learn the change in mass as a function of temperature and time. The equipment is also capable of conducting a simultaneous DTGA analysis. The type of heating cycle can be tailored to your sample (temperature ranges from 25 °C to 1100 °C), with various options for the surrounding gas atmosphere (air, O₂, and N₂). Please disclose the aim of your TGA measurement and the desired temperature program and atmosphere(s) upon ordering.
