Detecting and Quantifying BTEX and other Aromatic Compounds - Volatile aromatic compounds including 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.
