2.1 This method employs a sampling module and meter box to withdraw a 20-L sample of effluent gas containing volatile organic compounds from a station ary source at a flow rate of 1 L/min, using a glass-lined probe heated to 130 ± 5EC and a sampling method for volatile organic compounds (SMVOC) train.
For semivolatile analysis specifically, most environmental laboratories rely on gas chromatography for detection and quantitation. It is important to note that gas chromatography has been at the center of U.S. EPA’s strategy for monitoring organic contaminants since the early to mid 1970s.
Post cleaning, vials are assembled with PTFE/silicone septa and open-top polypropylene caps. VOA (EPA) Vials VOA vials meet EPA standards for volatile organic sampling. The 40 mL vials are available in clear (Type 1, 33 expansion) and amber (Type 1, 51 expansion) borosilicate glass.

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; Low molecular weights
