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 کاملInfluence of sampler configuration on the uptake kinetics of a passive air sampler.
Passive air samplers (PAS) are simple and cost-effective tools to monitor semivolatile organic compounds in air. Chemical uptake occurs by molecular diffusion from ambient air to a passive sampling medium (PSM). Previous calibration studies indicate that even for the same type of PAS, passive air sampling rates (R, m(3)(air)/d) can be highly variable due to the influence of a number of factors....

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 کاملTOPAS / TDS D – Badge-Type Thermodesorption Passive Sampler Based on Tenax for Air Sampling - Development Study
The TOPAS / TDS D system combines the advantages of the passive sampling of badge-type passive samplers with thermal desorption for sample transfer to the gas chromatography system. The large surface and the sampler’s short diffusion path permit high sampling rates. Use of thermal desorption as a sample transfer technique avoids the necessity for time consuming sample preparation and allows low...
