A hand held sampling apparatus and method are provided. The apparatus has a handle, a head connected to the handle and a mechanism for retaining a substrate on the head. The substrate is preferably a sheet-form flexible substrate which is mounted so as to present a collection portion thereof for collection of a sample. The substrate is preferably of a dimension so as to be readily fitted into the inlet portion of an analyzer. The apparatus enables an area to be sampled quickly and efficiently, while keeping a user's hands away from the surface, and this enables otherwise inaccessible areas to be sampled. It does not require any intermediate transfer steps, transferring a sample from a collection media to another substrate for subsequent analysis.

[ We claim:] [13.] A hand held sampling apparatus for collecting a sample of at least one of solid particles, aerosols, droplets and trace chemicals on a substrate which is in sheet form and comprises a central working portion and an edge portion substantially extending around the central working portion, for analysis in an analyzer, the apparatus comprising:a handle;a head having one free end and another end connected to the handle, the head extending from the handle and including a projecting body between said one free end and said another end around which the substrate is located; andretaining means adjacent said another end for retaining the substrate around and closely adjacent to the projecting body, for presenting the working portion for collection of the sample and for enabling mounting and removal of the substrate from the apparatus, the retaining means contacting only the edge portion of the substrate to secure the substrate to the sampling apparatus.
