Organic Chemistry Branch

The Organic Chemistry Unit is comprised of the Volatile Organics Group and the Semi-volatile Organics Group, which are responsible for analyzing environmental samples (including surface water, groundwater, soil, sediment, chemical spill and fish tissue) for the pesticide, semi-volatile and volatile organic parameters listed below using gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS) instrumentation. Detection levels are at the parts per billion and parts per trillion levels.
