A Passive Sampler for Atmospheric Particles
Preliminary investigation on the feasibility of size selective passive sampling for atmospheric particles was undertaken through laboratory simulated and outdoor sampling. The passive samplers used in the research were improved from passive sampler used for sampling atmospheric organic contaminants. Sampled particle size distribution was analyzed by MasterSizer 2000 laser particle size analyzer...

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 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 کاملField performance of the Chemcatcher passive sampler for monitoring hydrophobic organic pollutants in surface water.
Six field trials were carried out to assess the performance of the Chemcatcher passive sampler alongside spot sampling for monitoring priority hydrophobic organic pollutants (polycyclic aromatic hydrocarbons (PAHs) and organochlorine pesticides) in a wide range of conditions in surface water. The trials were performed in three European rivers: Elbe (Czech Republic), Alna (Norway) and Meuse (Net...
