Sampling Information Normal procedures for volatile organic compound (VOC) collection should be followed. Analysis requires two (2) 40 ml VOC vials per compound per analysis for δ 2 H and δ 13 C or four (4) 40 mL VOC vials per compound for δ 37 Cl (i.e. if you want to analyze TCE, cis-DCE and trans-DCE in one sample for both δ 13 C and δ 37 Cl, then please collect 3x2+3x4=18 vials per

Volatile Organic Compounds (VOC) Samples are collected in 40 mL VOC vials, which are supplied by the laboratory. Sample Collection and Preservation with Acid Collect all samples in duplicate. Two 40 mL vials are provided in the kit for each sample site
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
Glass vials for collection of water and soil samples for Volatile Organic Analysis. Borosilicate glass Clear vials for general analysis; amber vials for light-sensitive materials GPI thread, 24-400 Compliance Precleaned to meet or exceed EPA standards for volatile
1. Analysis of the blood sample is performed by equilibrium headspace analysis using SPME. For analysis, 3-ml of blood is transferred by gas-tight syringe from a blood collection tube to a headspace vial. The SPME fiber is inserted into the headspace of a
For this reason, volatile organic compound (VOC) samples collected for 1,4-Dioxane analysis are not to be -preserved.acid Sodium thiosulfate is used to neutralize oxidizers such as total residual chlorine. The Water Sciences Section supplies the following 401,4

Volatile Organic Compounds in Water NHANES 2001-2002 7 E. Unacceptable specimens The criteria for unacceptable specimen are a low volume (< 10 mL), failure to maintain sample temperature between 0 C and 10 C, suspected contamination, glass vial.
40mL vials (sampler may use wide mouth jars if sample not amiable to smaller vials) 2 QC 40 May 2003 fact sheet specifying procedures for the collection and handling by field samplers of soil samples for volatile organic analysis (VOA) in Region III ...
To assure representative samples and consistency in collection procedures, a specific sampler was designed to collect samples for analysis of volatile organic compounds in stream water. This sampler, and the collection procedures, were tested in the laboratory and in the field for compound loss, contamination, sample reproducibility, and functional capabilities.
skin and eyes. A respirator should be worn even when working outdoors if organic vapors are present. More hazardous sampling missions may require the use of supplied air and special clothing. 4.1.4 Cleaning of glassware In the analysis of samples containing
