Water samples should be taken in the appropriate volatile organic analysis vials with no headspace. Transfer should then be carried out from those sample vials to the headspace vials using a gas- tight syringe avoiding the use of pipettes.

The challenge falls on two parties: the field sampler, who takes the actual sample for analysis, and the laboratory bottle prep staff, who has to provide trip blanks for sample kits. Trip blanks are VOC vials filled with lab reagent water and travel with the sample kits as a control to monitor contaminate exposure during transit and storage and not from the sample source.
Volatile Organic Compounds (VOCs) Overview When collecting samples for volatile organics analysis, the most critical aspect of the collection process is the prevention of headspace at the top of the sample in the container. The presence of headspace (i.e. air

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).
