||Laboratory and field studies for VOST and SemiVOST have been performed to evaluate the performance of halogenated volatile and semivolatile organic analytes from Title III of the CLean Air Act Amendments (CAAA) of 1990. Laboratory tests were conducted to determine if candidate nonhalogenated CAAA analytes and pesticides could be analyzed by gas chromatography/mass spectrometry (GC/MS). Three spiking schemes were employed in the field evaluation study: Volatile organic compounds were spiked into VOST trains as a gaseous spike, and semivolatile organic compounds were spiked into SemiVOST trains either as a mixture of either Acid/Neutral compounds or Base/Neutral compounds. These two mixtures were evaluated in separate sampling runs to avoid losses due to known acid/base chemical reactions. This field evaluation study was performed at a clean source with low moisture levels and minimal background levels of organic compounds: Ten quadruple sampling (each) runs were performed for VOST, Acid/Neutral SemiVOST, and Base/Neutral SemiVOST. Statistical analysis of the results was performed according to the guidelines of EPA Method 301.
