Abstract
The use of a Dewar condenser placed on top of the supercritical fluid extraction off-line collection vial reduces analyte losses signifcantl y. Five groups of analytes (EPA-PAHs, alkanes, nitro-PAHs, fatty acid esters, and chlorinated hydrocarbons), all of them of environmental co ncern, were investigated and quantified by GC-FID/GC-ECD. Collection l osses were reduced to about 2%, with the condenser kept at -25 degrees C.
