METHOD 5021A VOLATILE ORGANIC COMPOUNDS IN VARIOUS SAMPLE

1.1 This method describes equilibrium-based static headspace preparation of volatile organic compounds (VOCs) in soil/sediment, solid waste, aqueous and water-miscible liquid samples for determination by gas chromatography (GC) or gas chromatography/mass spectrometry (GC/MS). This method is applicable to a wide range of organic compounds that

Volatile Organic Chemicals – General Information Volatile organic chemicals include components of petroleum based products and industrial solvents and chemicals. They may be associated with leaking underground tanks, improper disposal practices, leachate from landfills, discharge from chemical plants and other activities.

A comprehensive evaluation of the vial equilibration method

Nov 01, 1994 · Isooctane and dimethylsulfoxide caused a significant decrease in TCE metabolism. The vial equilibrium technique, as described herein, is relatively simple, rapid, and reliable, and may be applicable as a standard procedure for quantifying volatile organic chemical metabolism by different tissues of different species, including humans.

Instructions for Volatile Organic Compounds

Instructions for Volatile Organic Compounds. Volatile Organic Chemicals need to be sampled in 40 mL glass vials with a septum cap commonly referred to as VOA vials. If the vial contains hydrochloric acid use caution when handling and do not to rinse out the preservative at any time during sampling. When filling the vials, overflow slightly, so that a meniscus forms on the top of the vial.
