water/drinking water/ground water/surface water) for Volatile Organic Analysis (VOA) free of head space, or more commonly, air bubbles. The theory is that, after sample collection, any head space/air bubbles in the sample vial (standard 40 mL glass
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, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including
2008/2/1 · Volatile organic analysis vials are the recommended container for transporting aqueous samples containing dissolved-phase volatile organic compounds from the field to the laboratory (ASTM, D3694). However, the samples must be stored at 4 °C and analyzed within 14 days of collection to avoid loss of volatile organic compounds, such as PCE and TCE.
OI Analytical designs and manufactures instrumentation for chemical analysis. Data from our analytical instruments serve as the basis for informed decisions affecting human health and safety, environmental protection, industrial operations, and product quality.
