Personal Modular Impactors (PMI) - PM2.5, flowrate 3 L/min

The patented (U.S. Patent No. 7,334,453) SKC Personal Modular Impactors (PMIs) are designed for the highly efficient collection of PM10, PM2.5, or PM Coarse(PM10–2.5). The samplers are easy to use with a removable filter cassette and pre-oiled impaction substrate. PMI media changes are as easy as removing the filter cassette and replacing it with one already loaded with a 37-mm filter. The 25-mm pre-oiled impaction substrate mounts directly on top of the filter cassette and reduces particle bounce for high collection efficiency. A 25-mm filter may be used as an alternate impaction substrate for optional gravimetric or chemical analysis of particles. The PMI Coarse model and the Coarse Ring accessory include a second filter cassette to allow collection of particles sized between 2.5 µm and 10 µm.
