 Figure 2a. Examples of personal aerosol samplers. a. Open faced (top) and closed face (bottom) 37 mm cassette samplers. These are shown in acrylic copolymer (clear, non-conducting) material and are more prone to electrostatic losses. Other construction materials are available, including conducting plastic. Sampling flow rates range from 0.5 to 10 L/min.

Figure 2b. IOM inhalable sampler. This is the first sampler designed specifically to match the inhalable sampling convention. The sampling cartridge is shown on the right with the inlet, filter, and support grid from top to bottom. All dust entering the cartridge is collected and analyzed. Sampler is made of conductive plastic and operates at 2 L/min.
