ABSTRACT:
A method for enhancing supercritical fluid extraction of sample matrices which contain water. The method involves mixing the samples with an extraction enhancing aid comprising flux-calcined diatomaceous earth which increases the permeability of the sample in a supercritical fluid and controls water during the extraction procedure.
