網頁In thermogravimetry (TGA), weight change associated with a transition in the sample as a function of temperature is measured. For example, if water molecules of hydration can be removed thermally, they can be detected by apparatus for TGA. Practically, the sample is placed in a crucible, which is part of an automatic recording analytical balance. 網頁under isothermal conditions. Various purge gases (inert, oxidizing or reducing) can be used with TGA for more complete characterization purposes. PerkinElmer offers a variety of high performance TGA instruments to cover a wide range of applications and needs.

網頁Thermogravimetric analysis (TGA) directly measures weight change of a material as it is heated over a temperature range in a controlled atmosphere. If observing a weight loss, then it may be accompanied by off-gasses associated with volatilization of solvents or degradation of the material. 網頁Q600 offers an automated version of StepWise Isothermal (SWI), the classical technique for improved TGA resolution.
