TA Instruments Thermogravimetric Analyzer - modular TGA Q5000 FTIR
Thermogravimetric Analyzer (TGA) is a thermal weight-change analysis instrument, used in conjunction with a controller computer and associated software to make up a thermal analysis system.

The Thermogravimetric Analyzer measures the amount and rate of weight change in a material, either as a function of increasing temperature, or isothermally as a function of time, in a controlled atmosphere. It can be used to characterize any material that exhibits a weight change and to detect phase changes due to decomposition, oxidation, or dehydration.

TGA is working in conjunction with FTIR spectrometer
Fourier transform infrared spectroscopy (FTIR) is a technique which is used to obtain an infrared spectrum of absorption, emission, photoconductivity or Raman scattering of a solid, liquid or gas. An FTIR spectrometer simultaneously collects spectral data in a wide spectral range.
