Thermogravimetric Analysis (TGA) provides quantitative information on the change in mass of a sample as a function of time as it is heated cooled or held at constant temperature. The combination of TGA with a mass spectrometer (MS) or a Fourier transform infrared spectrometer (FTIR) allows the nature of the gaseous reaction products formed in the TGA to be investigated online.
Features and Benefits
- TGA-MS – High sensitivity coupled with very fast measurement – Extremely small amounts of substances can be detected. Ideal for the online characterization of all types of volatile compounds
- TGA-FTIR – High chemical specificity and fast measurement – Characterizes substances by identifying their functional groups, i.e. the class of substance. Ideal for the online measurement of substances that exhibit medium to strong infrared absorption
