VOLATILE ORGANIC CHEMICAL (VOC) SAMPLING PROCEDURE This brochure provides general information on how to collect a volatile organic chemical sample. Steps and procedures can vary depending on the laboratory that is used so you should follow the instructions that are provided by the laboratory you are using. The analytical methods for VOCs call

Wheaton TOC/VOC EPA vials for laboratory Wheaton standard formats TOC/VOC EPA vials-Lab Consumables These glass vial are used primarily for the collection and testing of aqueous samples for Total Organic Carbon (TOC).
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.
1 The term “volatile organic compounds” refers to low molecular weight compounds which possess boiling points below 200oC, are insoluble or slightly soluble in water, and have been traditionally analyzed by purge-and-trap methods. 1 USACE Sample Collection and Preparation Strategies for Volatile Organic Compounds in Solids (October 1998) Scope:

2.2 The sample plug is immediately extruded into a glass vial containing organic-free reagent water. The vial is immediately covered with aluminum foil and a modified septum cap. 2.3 The sealed vial containing the sample is hand-shaken for 10 - 15 sec and the sample is visually examined to ensure that complete dispersion of the sample in the
A major problem associated with sampling soil for volatile organic chemical analysis is the preservation of sample integrity during collection, storage, and shipment of samples to the laboratory. Soil sampling and storage practices for this type of analysis must be designed to minimize VOC loss due to volatilization and biodegradation.
