Abstract
Abstract An apparatus for extracting organic materials from a sample of a solid matrix containing such organic materials, the apparatus comprising an outer tubular member containing a permeable sample support positioned intermediate the first and second ends of the outer tubular member, and a method for the extraction of such organic materials by applying heat to one end of the outer tubular member while cooling the other end of the outer tubular member. Optionally a solvent is used in the extraction in conjunction with alternate heating and cooling of the ends of the outer tubular member.

Claims Analysis
Total Claims: 20
Claim 1
Independent Claim
146 words
An apparatus for extracting organic material from a sample portion of a solid matrix containing said organic material, said apparatus comprising: a. an outer tubular member having a first sealable end and a second sealed end; b. a permeable sample support means in said outer tubular member intermediate said ends; c. and inner tubular member extending through said sample support means and having a first end positioned between said sample support means and said first sealable end of said outer tubular member; and d. a valve means above said first end of said inner tubular member adapted to permit flow of fluids through said inner tubular member and out said first end of said inner tubular member and to prevent flow of fluids through said inner tubular member from said first end of said inner tubular member to said sealed end of said outer tubular member.
Claim 2
Independent Claim
146 words
