Apparatus for and method of collecting trace samples for analysis |
摘要 |
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.
