Continuous, intermittent and passive sampling of airborne VOCs

Abstract: Long sampling periods are often advantageous or required for measuring air quality and characterizing exposures. However, sampling periods exceeding 8 to 24 h using thermally desorbable adsorbent tube (TDT) samplers for the measurement of airborne volatile organic compounds (VOCs) face several challenges, including maintaining stable and low flow rates, and avoiding breakthrough of the adsorbent. These problems may be avoided using intermittent sampling; however, the literature contains few if any reports that… Show more

“…Perfluorocarbon tracers (PFTs) for air exchange rate (AER) determinations, and ETS tracers were measured using passive samplers containing Tenax-GR and Carbosieve SIII adsorbents [42]. These samples were collected in duplicate in the child's bedroom.…”

“…Details of the method and its performance have been described elsewhere (Jia et al, 2007, 2006). After sampling, tubes were transported to the laboratory and analyzed within 5 days using an automated thermal desorption system (Scientific Instrument Services, Inc., Ringoes, NJ) followed by gas chromatography/mass spectrometry (GC/MS, Agilent 6890/5973, Santa Clara, CA) for 96 target VOCs.…”

“…Personal, microenvironmental and ambient air samples for benzene are typically collected over an extended time period, 12 to 48 h, therefore do not identify peak concentrations [96]. Short term excursions in benzene air concentrations and exposures exist around activities close to sources [97].…”
