• Description:
  Experiments were performed that examined how the electrical conductivity of personal samplers and the manikin on which the samplers were mounted affected sampling efficiency. These experiments were done in a wind tunnel using a 7 µm Mass Median Aerodynamic Diameter (MMAD) aerosol with conductive Institute of Occupational Medicine (IOM) samplers and conductive and nonconductive 37 mm cassettes mounted on a life-sized manikin, which was conductive or nonconductive. The charge on the aerosol was neutralized for some experiments. Nonconductive samplers gave lower sampling efficiency than conductive samplers for both the conductive manikin and nonconductive manikin, and the nonconductive manikin gave lower sampling efficiencies with both conductive and nonconductive samplers. These effects were smaller at reduced levels of charge on the aerosol. It is important to consider the conductivity of the manikin when designing experiments to determine the sampling efficiency of personal samplers mounted on a manikin. [Description provided by NIOSH]
