ABSTRACT:
A sampling device for removing particulate matter from a gaseous medium by jet impaction including a base, an impaction stage carried by the base and a connector diffuser carried by the impaction stage. The impaction stage has an apertured plate for generating a prescribed velocity of the gaseous medium as it passes therethrough, and a collection member is positioned under the apertured plate against which the gaseous medium impinges to collect the particulate matter thereon. Frangible locking means connect the jet impaction, the base stage and the connector diffuser together so that they cannot be separated without destruction of the locking means to prevent reuse.
