40ml EPA Vials have long been the vial of choice for volatile organic (VOA/VOC) sampling and analysis. Our extensive range of sampling vials also includes 20ml and 30ml vials, available in clear or amber glass. Vials are available with a Hole-Cap & Septa for use with autosamplers, Solid Cap & Liner for transport and storage, or with No Cap.
Feb 27, 2019 · Volatile organic compounds (VOCs) are chemicals that both vaporize into air and dissolve in water. VOCs are pervasive in daily life, because they’re used in industry, agriculture, transportation, and day-to-day activities around the home. Once released into groundwater, many VOCs are persistent and can migrate to drinking-water supply wells.

Mar 28, 2022 · For example, the European Union uses the boiling point, rather than its volatility in its definition of VOCs. A VOC is any organic compound having an initial boiling point less than or equal to 250° C measured at a standard atmospheric pressure of 101.3 kPa. 5, 6, 7 VOCs are sometimes categorized by the ease they will be emitted.
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
