Recent studies suggest that volatile organic analysis (VOA) vials provide a low-cost and readily available zero headspace system for measuring aqueous-phase hydrolysis rates. This work involved measuring rates of PCE and TCE disappearance and the corresponding appearance of dechlorination products in water-filled VOA vials and flame-sealed

Because the roots are exposed to volatile organic compound contamination in the unsaturated zone or shallow ground water, the volatile organic compound concentrations in the tree cores are an indication of the presence of subsurface volatile organic compound contamination. Thus, tree coring can be used to detect and map subsurface volatile organic

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 bubble) in the same container can compromise the integrity of the sample results.
