Synthetic semi-volatile organic compounds (SVOCs) are widely distributed in the environment due to their ever expanding uses. But because some are hazardous, their presence in matrices such as indoor air, wastewater, fish tissue and marine sediment samples
Thermo Scientific Clear VOA Vials with 0.125″ Septa are designed for water sample collection for volatile organic analysis (VOA). Available with septum permanently bonded to the cap or unbonded for easy replacement. Perfect shoulder angle enables effortless
This blank represents the “trip” the volatile vials take from leaving ELLE with the bottle order to the field for sample collection and back to the lab for testing. The blank is created at the laboratory by completely filling the volatile vial container with lab grade deionized water and sealing the container.
Quality Environmental Containers. VOA VIALS are most often used for volatile organic compound analysis. Available in clear 33 expansion and amber 51 expansion borosilicate glass. Open top vials come assembled with polypropylene caps with low-bleed 0.125" PTFE/silicone septa inserted (.135" septa for E-series vials).
The analysis of volatile organic compounds (VOCs) in environmental water samples is usually performed by either headspace (HS) or purge and trap (P&T), with separation by gas chromatography (GC) and detection by mass spectrometry (MS).

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

Environmental Sampling Vials and Closures. Vials for use in environmental sampling; caps and septa designed for use with pre-cleaned environmental sampling vials. Products include kits and ampules, and may be available in several sizes and vial colors. Trust our low-level certified vials for Total Organic Carbon testing and sampling.
The compositions, spatial distributions, seasonal variations and ozone formation potential (OFP) of volatile organic compounds (VOCs) were investigated in the atmosphere of Haicang District, Xiamen City, Southeast China. Twenty-four types of VOCs were

3 The vials used for the analysis of BTEX and VOC are to be collected with no headspace; this is to minimize the loss of volatile compounds. All other glass bottles should always have a headspace to prevent breakage caused by shifts in temperature.
Compliance volatile organic contaminants (VOC) monitoring is part of the Phase II/V Rules. VOC monitoring requirements are stated in the Code of Federal Regulations 40 CFR 141.24, and can be found online at the Kansas Department of Health & Environment
