The Clean Air Act Amendments of 1990, Title III, present a need for stationary source sampling and analytical methods for the list of 189 compounds. EPA has used VOST and SemiVOST sampling and analytical methods for this type of sampling of organic compounds in the past, but these methodologies have been completely validated for only a few of the organic compounds. In the study, the applicability of VOST and SemiVOST techniques to the Clean Air Act halogenated compounds has been evaluated under laboratory conditions. The methods were evaluated first to determine whether the compounds could be analyzed successfully. For SemiVOST and VOST compounds, the analytes were analyzed by GC/MS techniques. Retention times for the analytes were determined, and reference spectra were generated so that primary quantitation ions could be selected. Recovery of the compounds from the sorbents was evaluated, and analytical detection limits were determined from spiked sorbents. Quadruple sampling trains were used to collect replicate samples for statistical evaluation of the dynamic spiking techniques for liquids (SemiVOST). The paper presents the results of the laboratory experiments.
