Personal Respirable Sampler (PRS)

Personal Respirable Sampler (PRS) Overview

These small, light-weight samplers are used for personal respirable particle sampling in dieselized coal mines to obtain size fractionated particle samples of coal dust and diesel soot. A respirable cyclone is used at the inlet to remove non-respirable particles. This is followed by a single-stage inertial collector with a cutpoint at 0.8 µm and a final filter. The cut-point is selected so that most (>90%) of the coal dust is collected by the inertial collector, while most (>90%) of the diesel soot is collected by the final filter (see diagram below). In the Model 210, shown on the left, an impactor is used as the inertial collector, and the Model 230 uses a virtual impactor as the inertial collector to prevent particle bounce. These samplers are available by special order only.
