ABSTRACT:
An integral, two-stage aerosol sampling head for collecting and separating irborne particulate contaminants into two size fractions is provided which comprises a moulded housing containing an impaction plate as a first stage for removing and collecting particles having an aerodynamic equivalent diameter (AED) greater than 10.mu.m in size and a filter as a second stage for removing and collecting particles having an AED less than 10.mu.m in size. The sampling head assembly of the invention eliminates the separate first-stage cyclone separator of conventional personal aerosol sampling assemblies used by coal mine operators and inspectors to monitor the quality of air in coal mines.
