Interface between a piece of baggage and a preconcentrator

Abstract

The present invention is an interface between a piece of baggage and a preconcentrator. The baggage-preconcentrator interface is able be secured to the opening in the baggage, such as an opening created by a zipper. The baggage-preconcentrator interface provides a convenient entry point from which to extract air from the interior of baggage. The shape of such interface corresponds to that of the preconcentrator, which collects constituents of air. The preconcentrator is inserted into the baggage-preconcentrator interface and an air sample is extracted from the interior of the baggage and through both the interface and the preconcentrator. As the air is extracted, the constituents of air collect in the preconcentrator. After collecting the constituents, the preconcentrator is inserted into a testing unit capable of detecting trace amounts of explosives, such as an ion trap mobility spectrometer. The testing unit analyzes the constituents and determines whether any of them are explosive.

What is claimed is:  
     
         1 . An interface between a preconcentrator and a piece of baggage, said interface comprising: 
 (a) a top securing member;    (b) a bottom securing member connected to said top securing member and forming a gap therebetween; and    (c) a recess having a perimetrical shape that corresponds to the perimetrical shape of the exterior of a preconcentrator, said recess comprising a vent.    
     
     
         2 . The interface of  claim 1  further comprising two clamps, wherein each of said clamps comprises a top lip connected to said top securing member and a bottom lip connected to said bottom securing member, thereby forming a gap therebetween.  
     
     
         3 . The interface of- claim 2  wherein the two clamps are diametrically opposed to one another.  
     
     
         4 . The interface of  claim 2  wherein the gap between said bottom and top lips creates an opening.  
     
     
         5 . The interface of  claim 3  wherein each of said clamps further comprises a lever connected to said top lip, thereby allowing the opening to expand and contract as said lever moves toward and away from the center of the interface, respectively.  
     
     
         6 . The interface of  claim 1  further comprising at least one securing hole within said recess.  
     
     
         7 . The interface of  claim 6  wherein said securing hole is complementary to an electrode of the preconcentrator.  
     
     
         8 . The interface of  claim 1  further comprising a first locking ring.  
     
     
         9 . The interface of  claim 8  further comprising a second locking ring opposite said first locking ring.  
     
     
         10 . An apparatus that serves as an interface between a preconcentrator and a zipper within a piece of baggage, wherein said zipper comprises two rows of teeth, said apparatus comprising: 
 (a) means for receiving a preconcentrator;    (b) means for air to travel through said receiving means; and    (c) means for gripping a portion of each row of teeth of a zipper within a piece of baggage.    
     
     
         11 . The apparatus of  claim 10  further including means for securing at least one post of said preconcentrator to said apparatus.  
     
     
         12 . The apparatus of  claim 10  further comprising means for securing a lock for said baggage to said apparatus.  
     
     
         13 . The apparatus of  claim 10  wherein said gripping means comprises two clamps, wherein each of said clamps comprises: 
 (i) a bottom lip;  
 (ii) a top lip creating a gap between said bottom and top lips, wherein said gap comprises an opening; and  
 (iii) means for enlarging said opening.  
 
     
     
         14 . The interface of  claim 13  wherein the two clamps are diametrically opposed to one another.  
     
     
         15 . An interface between a preconcentrator and a piece of baggage, said interface comprising: 
 (a) a recess having a perimetrical shape that corresponds to the perimetrical shape of the exterior of a preconcentrator, said recess comprising a vent; and    (b) two clamps, wherein each of said clamps comprises a bottom lip and a top lip for gripping a portion of the baggage.    
     
     
         16 . The interface of  claim 15  wherein the two clamps are diametrically opposed to one another.  
     
     
         17 . The interface of  claim 15  wherein the gap between said bottom and top lips creates an opening.  
     
     
         18 . The interface of  claim 15  wherein each of said clamps further comprises a lever connected to said top lip, thereby allowing the opening to expand and contract as said lever moves toward and away from the center of the interface, respectively.  
     
     
         19 . The interface of  claim 15  further comprising at least one securing hole within said recess.  
     
     
         20 . The interface of  claim 19  wherein said securing hole is complementary to an electrode of the preconcentrator.  
     
     
         21 . The interface of  claim 15  further comprising a first locking ring.  
     
     
         22 . The interface of  claim 21  further comprising a second locking ring opposite said first locking ring.
