The purge and trap method is applied for the analysis of volatile organic compounds (VOCs) in aqueous samples by purging the sample with inert gas and transferring volatile analytes to an adsorbent trap in a gas chromatograph (GC).

Screw Top Vials: Standard (4.6 mm) and large opening (6.0 mm) vials are available in both clear and amber glass. They come with a variety of closures and septa. 9 mm Screw Top Vials: These large opening (6.0 mm) vials have a unique thread design that allows you to screw on the caps, and still use them in a robotic autosampler.
As part of the protocol for sampling VOCs, one best practice includes the use of Travel or Trip Blanks to monitor the integrity of the samples. Is possible to contaminate volatile samples while in transit or storage. To address this, the laboratory, on request, will provide organic - free water, sealed in VOA vials to accompany the sample
For many years, stream samples for analysis of volatile organic compounds have been collected without specific guidelines or a sampler designed to avoid analyte loss. In 1996, the U.S. Geological Survey's National Water-Quality Assessment Program began aggressively monitoring urban stream-water for volatile organic compounds.
