Thermal extraction is a solvent-free extraction process, whereby volatile organics are thermally vaporized from a solid, semi-solid, or liquid matrix into a gas chromatograph for separation and detection.
The TEPI WorkStation combines Humble's Thermal Extraction Pyrolysis Inlet (TEPI) with a HP 6890 GC with flame ionization detection (FID) and/or mass selective detector (MSD).
