An apparatus for collecting particulates and vapours from a contaminated surface includes a manifold having at least one nozzle receiving gas from a supply and directing at least one jet of gas onto a target area of the surface thereby to dislodge particulates and vapours from the surface. The manifold also has an orifice therein, one end of which is adjacent the target area. A pump draws gas and particulates and vapours dislodged from the target area of the surface into the orifice thereby to collect the particulates and vapours for analysis. A method for collecting particulates and vapours is also disclosed. <IMAGE> |
