The Personal Environmental Monitor (PEM) is a small, lightweight, personal sampling device consisting of a single-stage impactor and an after-filter. Aerosol particles are sampled through the single-stage impactor to remove particles above the 50% cut-point of either 2.5 or 10 µm in aerodynamic diameter.
The Personal Environmental Monitor (PEM) is a small, lightweight, personal sampling device consisting of a single-stage impactor and an after-filter. Aerosol particles are sampled through the single-stage impactor to remove particles above the 50% cut-point of either 2.5 or 10 µm in aerodynamic diameter. These large particles are collected on a greased ring and are discarded after sampling. Particles smaller than the 50% cut-point pass through the impactor and are collected on a 37-mm after-filter. To determine personal exposure, the filter may be analyzed gravimetrically for particle mass and chemically for specific chemical compounds. A personal air sampling pump provides the necessary airflow through the PEM. Use the PEM for air pollution studies, indoor air quality assessments, and personal sampling for industrial hygiene applications (not an EPA reference method for ambient air).
