General description

Purge-and-trap is the method of choice for extracting and concentrating volatile organic compounds (VOCs) from almost any matrix. US EPA specifies guidelines for using purge-and-trap methods to process soil, sediment, and water samples. The technique is also used to extract VOCs from foods, beverages, vegetation, pharmaceuticals, petrochemicals, etc. The tubes used in purge-and-trap analyses are generally packed with multiple beds of various sorbent materials, so that a broad range of high and low molecular weight compounds, polar and nonpolar, can be trapped in a single tube.
