The term VOA (Volatile Organics Analysis) is often used in place of VOC. VOC vials may contain acid to act as a preservative depending on your lab and availability. If the VOC vials do contain preservatives use caution while handling the vials. Try not to breathe any fumes that come from the vials during sampling.
These HPLC and GC vials are available as snap, screw or crimp in style, 15uL to 20 mL in sample size, and various of low bleed and high-quality material composition. For GC, GC/MS applications where sample matrices contain volatile or semi-volatile analytes of interest, the most common choice are crimp style vials to limit sample contents
Thisfollowing sections deal separately with volatile organic chemicals (VOCs) and. semivolatileorganic chemicals (SVOCs).

Supplier: Restek Precleaned volatile organic analyte sampling vials are cleaned and assembled before delivery, and are lot traceable for guaranteed quality. Screw-thread or vial format Clear or amber color Glass fabrication 24 mm orifice Volume capacity ranges from 20 to 60 ml depending on model.
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.
Alibaba volatile organic analysis vials with PP cap To be used for environmental analysis, EPA vials must be clean and free of substances that might influence the analysis. Glass Vials that meet these requirements are called EPA vials, or sometimes VOA (volatile organic analysis) vials.
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.
Taking a VOC (Volatile Organic Chemical) Sample Properly - Alaska. Pack the sample in a styro- foam container or bubble wrap so the vials do not break. Ship it in to the lab immediately. Step Seven Check for Air Bubbles Turn the vial over and tap the cap on a hard surface. There should NOT be an air bubble in the sample.
