Fig. 5: ECL detection of amines in aqueous solutions using the streaming potential device.
a Dependence of the ECL intensity on the concentration of TPrA using an electrolyte-free MeCN/H2O (3:1 v/v) solution at the flow rate of 0.30 mL min−1. b ECL emission profiles obtained during the flow of a MeCN/H2O (3:1 v/v) solution containing different amines (1 mM each) at the flow rate of 0.30 mL min−1. c ECL emission profiles obtained using a fully aqueous system as the electrolyte: distilled water or tap water solutions containing 1 mM TPrA were injected into the flow cell at the flow rate of 0.30 mL min−1. All measurements were performed using the resin monolith no. 1 as the filling material. Error bar shows the standard deviation (n = 3).
