Abstract: A sample probe is provided for sampling aerosols within a wall cavity. The sample probe includes a hollow tubular body having a distal end, an intermediate portion, a proximal end and a central passageway. The distal end includes a sharp beveled point provided to inhibit the blockage of a distal open inlet if the distal end is positioned against an object. The probe further includes one or more holes projecting through the probe's tubular body, preferably positioned substantially adjacent to the probe's distal end. The probe further includes a radially projecting region adapted for sealing a hole or opening formed to obtain access to a wall cavity. Moreover, the probe includes a proximal open outlet adapted to connect to the inlet of an aerosol sampling cassette.

Abstract: An adaptable filter sampling device is provided for localizing the utilized area of a filter medium. The filter sampling device of the present invention includes a filtration cassette having an inlet port, a body portion having an internal cavity, and an outlet port. Positioned within the body portion across the internal cavity is a filtration medium having a predetermined pore size for collecting particles. In addition, the filter sampling device includes an interchangeable restrictor plate made in various forms to enable its use with commercially available filter mediums and filtration cassettes. The restrictor plate includes one or more portals for directing the flow of gases or liquids through the filter sampling device. Preferably, the restrictor plate is positioned anterior and abutting the filter medium in relation to the particle exposure so that a gas or liquid is directed to a defined localized area of the filter medium.
