Soil blank was prepared in the lab and used to test recoveries. Matrix Modifying Solution Oily material and organic sludge waste in soil inhibit the parti-tioning of the volatile target analytes into the headspace. Therefore recoveries will be low. This is called the
Clear vial designed for water sample collection for volatile organic analysis (VOA) Vial shoulder slope optimized to prevent air bubble entrapment Available in the standard 40mL size
Organic Chemistry Program. The Organic Chemistry Section analyzes for environmental contamination in water and soil, by organic pollutants. Our analytical capabilities target contaminants such as pesticides, herbicides, polychlorinated biphenyls ( PCB ), petrochemicals, chlorination dis-infection by-products, fumigants, plasticizers, and solvents.

4) Avoid filling the sample vials near a running motor or any type of exhaust system because discharged fumes and vapors may contaminate the samples. Avoid exposing the vials to gasoline or other organic vapors before and after sampling (don’t store VOC kit
Sampling Information Normal procedures for volatile organic compound (VOC) collection should be followed. Analysis requires two (2) 40 ml VOC vials per compound per analysis for δ 2 H and δ 13 C or four (4) 40 mL VOC vials per compound for δ 37 Cl (i.e. if you want to analyze TCE, cis-DCE and trans-DCE in one sample for both δ 13 C and δ 37 Cl, then please collect 3x2+3x4=18 vials per
