Passive sampling for volatile organic compounds in indoor air-controlled laboratory comparison of four sampler types.
This article describes laboratory testing of four passive diffusive samplers for assessing indoor air concentrations of volatile organic compounds (VOCs), including SKC Ultra II, Radiello®, Waterloo Membrane Sampler (WMS) and Automated Thermal Desorption (ATD) tubes with two different sorbents (Tenax TA and Carbopack B). The testing included 10 VOCs (including chlorinated ethenes, ethanes, and ...
متن کاملEvaluation of a passive air sampler for measuring indoor formaldehyde.
A passive air sampler, using 4-amino-3-hydrazino-5-mercapto-1,2,4-triazole, was evaluated for the determination of formaldehyde in indoor environments. Chromatography paper cleaned using a 3% hydrogen peroxide solution was experimentally determined as being the optimum absorption filter for the collection of formaldehyde (0.05 microg cm(-2) formaldehyde). From a linear-regression analysis betwe...
متن کاملEffectiveness of Portable Room Air Cleaners for Control of Volatile Organic Compounds in Indoor Air
IAQ T1S3) Eleven commercially available portable room air cleaners have been tested on a mixture of 16 representative volatile organic compounds (VOC) in a full-scale stainless steel chamber and their initial VOC removal efficiencies have been evaluated. These products use different gas-phase contaminant removal technologies including adsorption, photocatalytic oxidation under UV irradiation (U...
متن کاملCalibration and application of a passive air sampler (XAD-PAS) for volatile methyl siloxanes.
Because the atmosphere is key to understanding the environmental behavior of volatile methyl siloxanes (VMS), a variety of reliable air sampling methods are needed. The purpose of this study was to calibrate and evaluate an existing, polystyrene-divinylbenzene copolymeric resin-based passive air sampler (XAD-PAS) for VMS. Sixteen XAD-PAS were deployed for 7-98 days at a suburban site in Toronto...
متن کاملCharacterization of polymer coated glass as a passive air sampler for persistent organic pollutants.
The use of thin-film polymer-coated glass surfaces or POGs as passive air samplers was investigated during an uptake experiment in an indoor environment with high levels of gas-phase polychlorinated biphenyls (PCBs). POGs consisted of a micron thick layer of ethylene vinyl acetate (EVA) coated onto glass cylinders. The uptake was initially linear with time and governed by the air-side mass tran...
