The volatile organic compounds benzene, ethylbenzene, toluene and xylene (BTEX) occur naturally in crude oil and seawater near natural gas and other hydrocarbon deposits. Manmade BTEX sources include chemical manufacturing, vehicle emissions, accidental spills and underground storage tank leaks into soil and groundwater. BTEX monitoring is performed by laboratory gas chromatography (GC) and gas chromatography–mass spectrometry (GC-MS) in accordance with Environmental Protection Agency (EPA), American Society for Testing and Materials (ASTM) and other standard methods. These instruments are large, complex, and require specialist maintenance. This has restricted deployment of these instruments for the analysis of BTEX compounds at chemical production facilities and spill sites.View Resources
The G908 BTEX analyzer can detect and quantify components in the ppm to low ppb range using high pressure mass spectrometry (HPMS) in either total ion count (TIC) or selective ion monitoring (SIM) mode as well as by flame ionization (FID) detection. G908 combines results from these detector channels into a single report, significantly increasing productivity.
