The preparation of two metal-loaded silicas is presented. The first one, iron-8-hydroxyquinoline silica (Si-Ox-Fe) is used in a small pre-column for selective enrichment of catechol derivatives. The other one, copper-cyclam silica (Si-Cy-Cu) acts as stationary phase for outer-sphere ligand exchange chromatography. The on-line coupling of these two silicas makes the HPLC analysis of acid derivatives of catechol in urine more specific and the analysis can be done without any pretreatment of the sample. |
