The personal environmental monitor is a single-stage impactor with an after-filter. The impactor stage removes aerosol particles larger than the cut size (either 2.5 µm or 10 µm aerodynamic diameter), and the smaller particles are collected on the after-filter. Aerosol particles collected on the after-filter are available for gravimetric and/or chemical composition analysis. The PEM can be used to obtain personal exposure data while the wearer goes about his/her normal activities.
