An apparatus for collecting particulates and vapours from a contaminated surface includes a manifold having at least one nozzle receiving ga s from a supply and directing at least one jet of gas onto a target area of the su rface 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 g as 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 colle cting particulates and vapours is also disclosed.
