Abstract

A highly sensitive amperometric detector for the liquid chromatographic analysis of carbohydrates has been developed based on the optimization of the Ni content in a Ni-Ti alloy electrode. An optimum nickel content of 30 at.% was obtained from a signal-to-noise analysis in a flow injection experiment on glucose in 0.1 M NaOH. An optimum working potential of 0.5 V vs. Ag/AgCl was obtained from a hydrodynamic voltammogram. The glucose detection limit in the flow injection analysis was 11 fmol. The electrode was applied to an LC detector with a microbore column and the detection limit was 50 fmol. Copyright (C) 1999 Elsevier Science B.V.
