ABSTRACT:
A supercritical fluid extraction system and method for extracting a sample from a matrix by use of supercritical fluid and collecting components of the matrix in a solid phase extraction collection column. This system includes a variable restriction valve for depressurizing the fluid with entrained sample and an integral adapter directly connected at a first end with the valve and directly sealingly engaging the collector column and having a second end for passage of the depressurized fluid and sample with matrix components into the collector column.
