Solid phase microextraction field kit
First Claim
1. A field-deployable solid phase microextraction kit comprising:
- a casing having a lid section;
a plurality of solid phase microextraction (SPME) fiber/syringe assemblies; and
at least a plurality of hermetically sealed transport tubes located in said casing, each transport tube for sealably and securely retaining one of said SPME fiber/syringe assemblies and preventing cross-contamination with another one of said SPME fiber/syringe assemblies retained in another transport tube when carried together in said casing, wherein each of said transport tubes includes means located at an end of said transport tube for allowing sampling of an environment within said transport tube, to determine contamination of a retained SPME fiber/syringe assembly.

Abstract
A field kit for the collection, isolation and concentration of trace amounts of high explosives (HE), biological weapons (BW) and chemical weapons (CW) residues in air, soil, vegetation, swipe, and liquid samples. The field kit includes a number of Solid Phase Microextraction (SPME) fiber and syringe assemblies in a hermetically sealed transportation container or tubes which includes a sampling port, a number of extra SPME fiber and syringe assemblies, the fiber and syringe assemblies including a protective cap for the fiber, and an extractor for the protective cap, along with other items including spare parts, protective glove, and an instruction manual, all located in an airtight container.

14. In a SPME kit having at least one solid chase microextraction (SPME) fiber/syringe assembly, the improvement comprising:
-
at least one hermetically sealed transport tube for a SPME fiber/syringe assembly, said transport tube having a configured interior corresponding to an exterior of the SPME fiber/syringe assembly, whereby said assembly is secured within said transport tube; and
said transport tube including a seal in one end through which an interior of said transport tube could be tested to determine contamination of the SPME fiber syringe assembly when retained in said transport tube. - View Dependent Claims (15, 16, 17)
