Patent Number Title Of Patent Date Issued
7334453 Modular particulate sampler February 26, 2008
A gas sampler includes an impact disc for removing larger particles from a gas flow drawn by a pump and a filter for capturing smaller particles, also positioned in the flow path. The sampler is conveniently dissembled and reassembled to remove and replace the impact disc and the filter.
7073402 Air sampler with parallel impactors July 11, 2006
An air sampler is designed for a predetermined flow rate. The air flow is admitted to at least two impactors operating in parallel. Preferably the inlet nozzles and the outlet orifices of each impactor are sized to achieve predetermined cut-off sizes of particles; preferably the comp
6607581 Passive sampling badge August 19, 2003
