electrochemical oxidation (a potential of 0.75V) using a electrochemical detector as post-column
reactor (Fig. 1.2.16) [225]. As the fluorescence intensity of PSP oxidized products is the strongest at pH
5 not under alkaline conditions, either method requires neutralization with introduction of diluted acetic
acid in flow after post-column oxidization. The major drawback of basic electrochemical oxidation was
the noisy baseline signal, caused by fluctuations in flow from the post-column pumps and thus variation
in the effluent composition.
