Distinguishing catecholamines: Dopamine determination in the presence of epinephrine in water/acetonitrile mixtures

A novel strategy for the simultaneous discrimination of dopamine and epinephrine by cyclic square wave voltammetry implemented with a customized potentiostat

“…Optimization of conditions for the determination of DA and EP by CSWV DA and EP underwent proton-coupled electron transfer (PCET) throughout their redox processes, which makes their redox potentials highly pH dependent. 36 Furthermore, there was a significant correlation between pH and the specific intramolecular cyclization process of catecholamines. 32 Thus, we investigated the effect of pH on CSWV of DA and EP in the range of 6.6-8.2 (0.1 M PBS).…”
