<abstract displayLabel="Summary">The reduction in sensitivity of the photovac TIP, TIP-1, and the H-NU101 total organic vapor analyzers equipped with potoionization detectors (PID) to toluene and gasoline in the presence of methane was examined. The results showed an exponential decrease in detector sensitivity, with a reduction of about 30% for 0.5% methane and 90% for 5% methane</abstract>
