Mar 31, 2020 · The analytical data resulting from this study show that analyte loss in methanol preserved vials received by the laboratory at temperatures exceeding the required 10°C is insignificant. Some volatile compounds in water, under zero-headspace, may exhibit sorption or degradation. Storage temperatures greater than 10°C may promote degradation of

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
In an environmental analysis context, the VOC designation, or volatile organic contaminants , generally refers to the analysis of compounds in environmental samples with the following chemical properties:+. Low boiling points (below 200°C) Low vapor pressures. Low-to-medium water solubility. Organic compounds.
