The patented‡ SKC IMPACT single-stage inertial impactor is designed for the efficient collection of PM10, PM2.5, or PM Coarse (10-2.5) in ambient air. A sampling pump operating at 10 L/min draws PM through the impactor; larger particles are captured on a disposable pre-oiled impaction disc while smaller particles collect on a 47-mm filter. IMPACT media changes are as easy as removing the filter cassette and replacing it with one already loaded. The impaction disc fits into the top of the cassette. IMPACT's higher flow rate requirement provides increased sensitivity for low levels of PM. For sampling efficiency data, go to

IMPACT and the Leland Legacy Sample Pump

While IMPACT can be used with any pump at 10 L/min, partnering IMPACT with the Leland Legacy sample pump provides a highly efficient sampling system. The quiet, fully programmable Leland Legacy pump can provide a constant 10 L/min flow rate for 24 hours making it ideal for environmental monitoring or indoor air studies. IMPACT and the Leland Legacy Sample Pump are both included in the DPS Sampler System.
