Recent Advances in Microextraction Methods for Sampling and Analysis of Volatile Organic Compounds in Air: A Review
Human exposures to volatile organic compounds (VOCs) are associated with a wide range of health problems. Due to these adverse effects of VOCs on the human health, determination of trace levels of VOCs is very important for accurate assessment of indoor and outdoor exposure. Solid phase microextraction (SPME), needle trap device (NTD) and hollow fiber- liquid phase microextraction (HF-LPME) are...

متن کاملPassive 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 کاملVolatile Organic Compounds Monitoring for Semiconductor Foundry Clean Room Air
Air samples were collected in consecutive days using Summa canisters from semiconductor foundry clean rooms and air entrances. By coupling a NuTech preconcentrator with an Agilent GC-MS, an optimized method for qualitative and quantitative analysis of VOC compounds was developed. Method detection limit (MDL), blank spike (BS) and blank spike duplicate (BSD), etc. were estimated for method valid...
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...
