Description:
Fractionation and cleanup of sample extracts prior to instrumental analysis is usually accomplished by column chromatography, gel permeation chromatography, or acid-base partitioning. n this report, the results of a study are described in which we investigated the application of solid-phase extraction (SPE) cartridges containing Florisil, alumina, silica gel, and diol to the fractionation and cleanup of sample extracts. he compounds investigated included organochlorine pesticides and polychlorinated biphenyls listed in SW-846 Method 8080/808l, phthalate esters listed in Method 8060, and phenolic compounds listed in Method 8040. raft protocol for the use of SPE cartridges for sample extract cleanup was prepared and tested with spiked synthetic matrices and with spiked extracts of real samples. he results of this study indicate that such use of SPE cartridges is feasible for a variety of matrices and target compounds.
