ABSTRACT:
A sampling nozzle is operatively coupled to a vacuum device and has a tubular coring member removably mounted at its upper end for extracting a sample of material from goods suspected of being hazardous. A canister is removably carried in the nozzle beneath the coring member in co-active, in-feed relation therewith for receiving the extracted sample. Air passages through the nozzle sidewall cooperate with a conical shroud carried on the upper end of the nozzle to create a blanket of air vacuum surrounding the coring member and the area around which the sample has been extracted. A high efficiency particulate filter may also be provided between the nozzle and the vacuum device. The sample is extracted while the surrounding blanket of air vacuum is active by placing the sampling nozzle against the goods to be sampled with the coring member in firm contact with the surface of the goods and pressing the nozzle causing the coring member to penetrate the material. The blanket of air vacuum surrounding the coring member draws airborne particulate material, vapors, and fumes in the vicinity of the extracted sample into the nozzle to be filtered. The cored sample falls through the coring member into the canister. The coring member is removed from the nozzle, and a compression spring ejects the container partially outward of the nozzle and it is capped under the same vacuum blanket to sealingly contain the extracted sample after which it may be safely transported to a convenient location for further analysis.
