A desolvation device was connected to a microcolumn (40 mm X 3.0 mm i.d.) in which 8-hydroxyquinoline-5sulphonic acid was immobilized on the substrate of active carbon-silica gel. The analyte and 1.0 M sodium acetate-acetic acid buffer solution (pH 5.6) were mined and pumped through the microcolumn.
