This study is a follow-up to previous work conducted at Battelle for the purpose of evaluating the Gossen PAS 1000i (and the more recent Model 1002i) for real-time analysis of particulate PAH in indoor air. Specific tasks conducted as part of this work included further tests of the response of the analyzer to a number of 2- to 4-ring PAH and benzene vapors at high and low relative humidity levels, and an evaluation of the noise and ozone output of the analyzer. A cigarette smoke generator was also developed for field evaluations of the PAH analyzer. Despite the inherent variability in the cigarette combustion process, the smoke generator could be used in the reasonably reproducible manner to verify operation of a PAH analyzer in the field. The effect of elevated or depressed temperature and humidity operating conditions on response of the PAH analyzer was also studied. The aerosol transmission efficiency through the PAH analyzer was also determined for monodisperse particle sizes over the size spectrum, 0.034 - 0.32 micrometers. As a continuation of work conducted previously, a systematic study of the response of the analyzer to laboratory generated non-PAH aerosols was also conducted. This work also included a small pilot study conducted concurrently with a PAH in house dust study that was the focus of a separate EPA Work Assignment.
