Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified,
Generally used for volatile organic compound analysis and sample storage, our 20mL, 40mL, and 60mL VOA vials are available in clear or amber borosilicate glass with Solid Top PTFE-lined closures. The assembled vials are available Standard (QC inspected), Precleaned, or Precleaned/Certified in accordance with recommended E.P.A. protocol.
The measurement of volatile organic compounds (VOCs) in groundwater is an important test that is conducted by numerous laboratories throughout the world. In more recent prominence is the need to test samples for pre-drill and post-drill aquifer monitoring in localities where hydraulic fracturing for shale gases is occurring.
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
