Abstract: A transportable automated analyte extraction apparatus is provided which includes at least an extraction fluid supply in communication with an extraction chamber, and a collection vessel in communication with the extraction chamber, wherein the extraction chamber includes a sample cartridge. The analyte extraction apparatus preferably utilizes supercritical extraction fluids and a modifying reagent, collectively called the extraction solution, to extract analyte from a sample. The extracted analyte can then be subjected to subsequent testing.

Abstract: A method for extracting and detecting analytes that are metabolically associated with biological samples, as well as, for distinguishing between those which are environmentally associated and those which are metabolically incorporated is disclosed.
