Title:
AEROSOL SAMPLING SYSTEM
Document Type and Number:
WIPO Patent Application WO2004047951
Kind Code:
A3
Abstract:
A system for sampling air and collecting particulate of a predetermined particle size range. A low pass section has an opening (101) of a preselected size for gathering the air but excluding particles larger than the sample particles. An impactor section (103) is connected to the low pass section and separates the air flow into a bypass air flow that does not contain the sample particles and a product air flow that does contain the sample particles. A wetted-wall cyclone collector, connected to the impactor section, receives the product air flow and traps the sample particles in a liquid.
