Pacific Vial sells EPA vials for environmental industry lab use. Flat bottomed EPA vials are available in 20 ml, 40 ml, and 60 ml sizes. These vials are made of chemically inert clear Type I borosilicate 33 expansion glass, or for light sensitive samples, of amber 51 expansion glass.
This approach allows for detection levels in the low microgram/kilogram range (< 10 µg/kg) for most fuel-related hydrocarbons and slightly higher levels (25 µg/kg to 50 µg/kg) for some halogenated compounds. Closed system purge-and-trap by method 5035. This method is designed to minimize the loss of VOCs from soil.
Soil : 125 mL glass jar with Teflon (or foil) lined lid Water : (minimum of) 2 40-60 mL septum capped glass vials Preservation : Soil : Samples are not preserved. When the analysis includes methanol, or to meet low RLs, it is suggested to collect the 4
Unlike other methods, the En Core® Sampler is the quickest way to collect soil VOC samples that comply with the latest protocols, including US EPA 5035. The En Core is fast and easy, producing more representative and consistent samples every time with minimal loss of volatiles.

NOTE- The actual concentration of the high standard is 100ppb * 10.0mL/100mL or 10ppb, well within the linear range of the Hydra II AA. Figure 2: Calibration Curve Four quality control soil samples were obtained from NIST2 for analysis. Some sample and
2000/4/19 · EPA has permitted the use of methanol preservation for low level analysis if the target analyte(s) can be quantitated below 200 µg/kg. As a result, laboratories must demonstrate their ability to detect below 200 µg/kg to the client and ADHS. Samples preserved
