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. Aijiren flat bottomed EPA vials are available in 20, 30, 40 and 60ml sizes, suitable for water or soil samples.
EPA Method 1614A was developed to determine polybrominated diphenyl ether (PBDE) congeners in aqueous, solid, tissue, and multi-phase matrices. These ethers are used as flame retardants. The method uses isotope dilution and internal standard high resolution gas chromatography/high resolution mass spectrometry (HRGC/HRMS).

Oct 18, 2021 · This attenuation factor is used for all soil gas data, as additional information collected after development of the 2002 draft vapor intrusion guidance (EPA 2002) suggests that external soil gas samples need to be evaluated as conservatively as target sub-slab gas samples (EPA 2010). The exposure parameter variables are defined in Table 1.
