Stable Modified Electrodes for Use in Amperometric Detectors in Flow Systems

摘要: Practical analytical applications of modified electrodes, particularly examples that are based on mediated reactions, have been slow to emerge. Only a few attempts, other than our work which is described herein, apply such electrodes flow systems reported. Baldwin and co-workers used an electrode was prepared by mixing cobalt phthalacyanine with carbon paste for the determination hydrazine1 some sulfhydryl compounds2 high performance liquid chromatography amperometric detection. Although results were promising, day-to-day stability without mechanically renewing surface somewhat limited.
