Applications of tga-ms

摘要

Thennogravimetric analysis (TGA) measures weight lost during thermal or oxidative decomposition. VA-die this technique is an excellent tool for determining the relative amounts of each component of a material, it does not give any indication of the chemical content of those components. Chemical content can be determined by sampling the gas evolved from the sample decomposition using a variety of techniques. Mass Spectrometry (MS) measures the mass to charge ratios of the input gases to determine the molecular weights of the species involved. A heated transfer line couples the outlet of the TGA to the MS inlet for optimal sampling of the off-gases.
