摘要：A hand held sampling method is carried out using apparatus have 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 prent 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 is manipulated so that the collection portion of the substrate travers surfaces of interest. The substrate is then removed and placed at the inlet of an analyzer for desorption of a sample. The apparatus enables an area to be sampled quickly and efficiently, while keeping a ur's hands away from the surface, and this enables otherwi inaccessible areas to be sampled. It does not require any intermediate transfer steps, transferring a sample from a collection media to another substrate for subquent analysis.
