  Analysis of volatile organic compounds collected in humid conditions: development of a method to remove humidity from gaseous samples, Descrição: The aim of this study was to develop a method to remove humidity from VOC samples prior to analyzing them. Different types of commercial sampling bag films were investigated: Tedlar (PVF, polyvinyl fluoride), Teflon (FEP, Fluoride ethylene-propylene), Flexfoil and Nalophan (PET, polyethylene terephtalate). These sampling bags were filled with humid air and placed into a chamber flushed with a dry air stream. Tedlar and Nalophan bag samples containing 10 L of humid air (80 % relative humidity at 20 C) were dried respectively in 7 h and 3.5 h. Flexfoil and Teflon have not shown any interesting humidity diffusion. Parameters which increase the humidity diffusion are a high humidity gradient between inside and outside the bag, a high temperature and an important surface/volume ratio of the bag. It was checked that this SWR method did not involve any VOC loss (with methanol, ethanol, n-propanol, acetone, n-hexane, dichloroethane, trichloroethylene, methyl isobutyl ketone, butyl acetate, toluene and ethylbenzene). Tedlar bags filled with VOCs at 10 ppmv and 500 ppbv levels, did not show any VOC loss, however, at 10 g/m3, the quantification of some compounds was affected by the background pollution of Tedlar bags. With Nalophan bags, no significant VOC loss was noticed at10 g/m3. . , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Graduação: (3) / Mestrado acadêmico: (1) . , Integrantes: Sandra Paule Beghi - Coordenador., Financiador(es): École des Mines d´Alès - Remuneração.
