2.1 Sample Collection and Headspace Vial Preparation 2.1.1 Water samples - A 40-mL VOA vial is filled with water. The water sample can be fixed by addition of a chemical preservative to the vial. When the vial is headspace free, it is capped. At the laboratory, that vial is sub-sampled into a headspace vial. A matrix
Sampling Reference Guide. Compliance with analysis-specific container and preservation requirements is a critical component to the sample collection process. In order to provide assistance to our clients during this stage of their projects, Alpha has a number of sampling reference guides which provide information on appropriate container type
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:
refrigerated storage. After 10 weeks of storage the blood often begins to thicken and is therefore difficult to handle. Even though analytical results may not change over this time, samples may be less amenable to analysis. Certain volatile organic compounds are produced naturally, and metabolism may alter their concentration with storage.
Description: Type I borosilicate glass vial s contain a chemical preservative to maintain sample integrity until volatile organic analysis can be performed. SDS Certificates ,89094-180CS,89094-160CS,89094-172CS,89094-182CS,89094-178CS,89094-158CS
