The system couples a TGA with an FTIR and a GC/MS instruments. TG-IR-GCMS/MS is one of the most powerful approach to EGA, to reach extra information easier and faster! This configuration is capable of analysis of unknown mixture to determine the primary components and identify additives or contaminants.
The evolved gases generated from the sample analyzed in the TGA furnace are transferred through the interface into the IR cell for the spectral analysis, then the gas passes to GC for separation and into the MS for final detection and identification of peaks.
Evolved gases can also pass directly to the MS without the GC separation.
GCMS injection block design avoids capillary cloggings, carry over and cold spots that could compromise the analysis. The system allows real-time analysis thanks to the GC instrument which can separate and detect very low levels of material in complex and unknown mixtures.
