Oxford Style Sleeve for Sample Cup

Abstract

This invention relates to the design and construction of a novel sample cup sleeve for a sample cup for use in XRF Spectroscopy.

What is claimed: 
     
         1 . A sample cup sleeve for a sample cup used for retaining a sample to be analyzed spectrochemically said sample cup sleeve comprising:
 an outer member comprising a top open end, a bottom open end, a flanged upper rim, frst projections about said flanged upper rim, and second projections about the lower body of said outer member;   wherein said outer member is dimensioned to frictionally fit circumferentially about an inner member; and   wherein a thin-film of material is secured across a bottom open end of said inner member by application of said outer member to contain a liquid sample for spectrochemical analysis.   
     
     
         2 . The sample cup sleeve according to  claim 1 , wherein said frst projections are dimensioned to index against a hard planar surface to position a fully assembled outer member over said inner member such that there is about 0.005″ clearance between the thin film covering the bottom open end of said inner member and a planar surface when the sample cup assembly is returned to an upright position. 
     
     
         3 . The sample cup sleeve according to  claim 1 , wherein said second projections are semi elliptical. 
     
     
         4 . The sample cup sleeve according to  claim 1 , wherein said second projections are squared. 
     
     
         5 . The sample cup sleeve according to  claim 2 , wherein said second projections are semi elliptical. 
     
     
         6 . The sample cup sleeve according to  claim 2 , wherein said second projections are squared.
