The PQ200 is designed to meet exacting criteria for collecting 24-hour samples of ambient "Fine Particulate," according to the U.S. National Ambient Air Quality Standards (NAAQS), published July 18, 1997.
The Very Sharp Cut Cyclone (VSCC) has replaced the WINS impactor and allows 30 days between cleaning intervals. Further details may be viewed on an individual page. Existing PQ200 samplers may be converted.
PM2.5 (particles less than 2.5 micrometers in aerodynamic diameter) is collected on 47 mm PTFE membrane media at a volumetric sample rate of 16.67 Lpm after being size discriminated through two U.S. EPA designed inertial separators. Ambient temperature and barometric pressure measurements are made at actual sample conditions. A microprocessor and sophisticated volumetric flow control system are integrated to maintain precise sampling parameters while sampling data are continuously logged into the processor memory. Five minute actual ambient temperature and pressure conditions with volumetric sample flow rate, filter temperature, and pressure are recorded. Measured values and identification of flags indicating any anomalies are recovered by the operator by downloading a sample summary to a laptop or handheld computer. EPA's audit program makes exclusive use of the PQ200A version of the sampler. This item is available to all authorities and individuals who wish to sample or audit under EPA stringent guidelines.
