State for this dielate. Several pieces of evidence can be offered polarography and cydic voltammetry (CV) of the Co(in)A3oGI) electrode process for the complex in the presence of dissolved oxygen dearly point to a chemical reaction following the electron transfer. The potoitial of the Co(lII)/Co(II) process is shifted towards less negative values and the cydic voltammetry confirms, from the ratio of the cadiodic to anodic peak intoisity (ipdipa), that the Co(ni)/Co(lI) dectron transfer is followed by a chemical reaction [12,13]. 

The amperometric detection uses less than 10% of the analyte in the flow cell, unlike the coulometric detector, and can be operated in a pulsed mode (cydic voltammetry, with a gold working electrode) in addition to the constant potential mode. The pulsed mode helps cleaning the working electrode.
