Volatile Organic Compounds (VOCs)

Volatile Organic Compound Testing

Volatile organic compounds (VOCs) are organic chemicals that have a high vapor pressure / low boiling point. Common sources of VOCs are gasoline, dry cleaning fluids, paints, adhesives, and industrial solvents.

The concentration of Volatile Organic Compounds (VOCs) are determined using Purge & Trap (P&T) sample concentration and Gas Chromatography – Mass Spectrometry (GC-MS).

Method 8260 is used when analyzing surface and ground water as well as solid sample matrices. Method 624.1 is used for wastewater samples.  The procedures are very similar, however the reported compound lists are somewhat different.

Drinking water is typically analyzed by method 524.2.  The conditions used in this method enables a lower detection limit to be reached. This provides results that meet drinking water regulatory limits or MCLs.

Lower detection limits for several groundwater contaminants are available, by utilizing a “Low Level 8260 modified” procedure which uses SIM techniques. Please contact us if you have questions about this technology.
