“…While metal/metal oxide systems are commonly used in classical potentiometric mode in combination with a reference electrode to generate a potential reflecting the pH [44,[57][58][59][60], it is also possible to employ them in amperometric mode in which a pH sensitive voltammetric signal is used, the peak potential of which is used to indicate the pH [61][62][63]. One attraction of this approach is that the measurement generates a current-voltage plot the shape of which allows the assessment of the 'quality' of the measurement and hence the reliability of the data.…”

“…Therefore, the majority of works using EGFET as part of a sensor describes it as a pH-sensor 3,[18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33] . PH monitoring and control, for itself, are quite important.…”
