Transport number dependence on ionic mole fraction. Ejections of 5 mM DA and 5 mM HQ in NaCl (n=6) were performed at 150–2000 nA and ejection quantities were determined by liquid chromatography. The observed transport number was calculated by the fraction of the ejection current accounted for by the ejection of DA (green circles). After subtracting the DA ejected due to EOF, transport numbers were recalculated (blue squares). The predicted transport number due to migration (Equation 1) is represented by the dotted blue line.
