Personal Modular Impactor (PMI)
The patented SKC single-stage Personal Modular Impactors are designed for the highly efficient collection of PM10, PM2.5, or PM Coarse (PM10-2.5). The 25 mm pre-oiled impaction disc 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 alternative impaction substrate for optional chemical analysis of particles. The PMI Coarse model includes a second filter cassette to allow collection of particles less than 10 µm but larger than 2.5 µm.
