A novel multiresidue method has been developed for quantitation of TBZ, the metabolite 5-hydroxythiabendazole (5-OH-TBZ) in raw cow s milk. The 5-HS04-TBZ was hydrolyzed quantitatively under acidic conditions to 5-OH-TBZ. The TBZ and 5-OH-TBZ were extracted from milk at pH 8.0 with ethyl acetate, followed by cleanup of the extract on a cation-exchange solid-phase extraction column. Analytes were separated with a cation-exchange stationary phase ... [Pg.587]

Matantseva and co-workers87,101,103 separated the major opium alkaloids on a pellicular sulfonic acid cation-exchange stationary phase, using a pH 4.5 phosphate buffer containing 30% acetonitrile as mobile phase. [Pg.298]

Depending on the ionic charge(s) of the solutes to be separated, anion or cation exchange stationary phases must be used. Common ion exchange support materials include silica, poly(styrene-divinylbenzene), and cellulose. Common anion exchange groups anchored to these supports include 1°, 2°, 3°, and 4"" amines.

The extensive use of reversed phase ion-pair HPLC in peptides has meant that some aspects of ion-exchange HPLC are not being exploited, e.g. for peptide mapping. The isocratic separation of the two desired components from a tryptic digest of an epidermal factor fusion peptide can be achieved using a cation-exchange stationary phase in combination with a step-wise gradient of sodium chloride in...
