IOM Sampler

The IOM Multidust sampler is the preferred sampler for HSE Method MDHS 14/4. The patented IOM Sampler houses a reusable 25 mm filter cassette that holds a specified filter for the collection of inhalable particles. When attached to a personal sampling pump operating at 2 L/min and clipped near a worker's breathing zone, the IOM effectively traps particles up to 100 µm in aerodynamic diameter. This collection method closely simulates the manner in which airborne workplace particles are inhaled through the nose and mouth. Both the plastic cassette and the filter are pre- and post-weighed as a single unit for gravimetric analysis.
