A miniature solid phase microextraction (SPME) holder. The miniature holder enables transportation and field use of SPME fibers which are very fragile and will break with the slightest impact. Also, the holder prevents cross contamination of samples during transport. The SPME holder consists of a barrel with two end caps, and includes a plunger that is connected to a commercial SPME fiber assembly, one end cap filing over the SPME needle on one end of the barrel and the other end cap fitting over the plunger. The end caps are provided with seals that give the holder a hermetic seal. The holder enables effective field use for the collection, isolation, and concentration of trace amounts of residues air, soil, etc. |
