Thermogravimetric analysis (TGA) measures the amount and rate of change in the mass of a sample as a function of temperature or time in a controlled atmosphere such as nitrogen, air, oxygen, argon. The technique can analyze materials that exhibit either mass loss or gain due to decomposition, oxidation or loss of volatiles (moisture, solvents, greases).
In addition, TGA Q500 can be adapted for evolved gas analysis with either FT-IR, MS, or GC/MS.
