The rugged and reliable EGA is an optional, quartz-lined furnace for the Q500 or Q50. The liner is essentially chemically inert to products produced from decomposition of the sample, resistant to adsorption of off-gas products, and its reduced internal volume ensures rapid exit of these materials from the sample chamber. These features make the EGA an ideal furnace for use in combined TGA/MS or TGA/FTIR studies. TA Instruments offers a 300 amu bench-top, triple-filter, quadrupole mass spectrometer with a heated capillary interface, and TGA module-specific interface kits for its Q5000 IR, Q500 and Q50 modules. A mass spectrum database is also available. A variety of FTIR suppliers provide gas cells and interfaces for use with all our TGA modules.
