Feedback-amplified electrochemical dual-plate boron-doped diamond microtrench detector for flow injection analysis

Résumé

An electrochemical flow cell with a boron-doped diamond dual-plate microtrench electrode has been developed and demonstrated for hydroquinone flow injection electroanalysis in phosphate buffer pH 7. Using the electrochemical generator-collector feedback detector improves the sensitivity by one order of magnitude (when compared to a single working electrode detector). The diffusion process is switched from an analyte consuming "external" process to an analyte regenerating "internal" process with benefits in selectivity and sensitivity.
