Method Evaluation Study: The Application of SemiVOST to the NonhalogenatedSemivolatile Organic Compounds from the Clean Air Act Amendments

摘要

A laboratory study and two field studies were performed to evaluate theapplication of the Volatile Organic Sampling Train (VOST, EPA Method 0030) to the volatile halogenated organic compounds (approximately 35 compounds) listed in the Clean Air Act Amendments (CAAA) of 1990. Subsequently, a laboratory study was performed to assess the feasibility of the application of the VOST methodology to the volatile nonhalogenated organic compounds listed in the CAAA (approximately 20 compounds). Quadruple VOST trains were run in the field, with dynamic spiking of the volatile analytes from a certified cylinder into two of the sampling trains. The bias and precision of the VOST sampling and analytical methodology applied to each of the volatile organic analytes were evaluated.
