A normal thermogravimetric analyzer is made of a precision balance which has a sample pan located inside a furnace which has a programmable Regulate temperature. The temperature is normally increased at frequent price (or for a few applications the temperature is controlled for a continuing mass loss) to incur a thermal reaction.
Quasistatic thermogravimetry: In This method, the sample temperature is elevated in sequential steps separated by isothermal intervals, through which the sample mass reaches balance prior to the start of the subsequent temperature ramp.
