RESUMEN

A gas chromatographic method using nitrogen-selective detection for the quantitative determination of nanogram amounts of chlorimipramine, chlorpromazine and their nor1 and nor2 derivatives in plasma is described. Derivatization with trifluoroacetic anhydride of nor1 and nor2 metabolites allowed the chromatographic separation of these compounds. A three-step solvent extraction procedure was performed using n-heptane containing 1% isoamyl alcohol and n-hexane and compared with a plasma clean-up procedure using C18 Sep-Pak cartridges. The two procedures were characterized by similar degrees of precision. The use of C18 Sep-Pak cartridges, however, produced a significant time and material saving over the conventional extraction method.
