Illustration of imaging the variation of thickness of ECL layer (TEL) with increasing the concentration ratio of (Ru(bpy)32+) to TPrA using ECL microscopy.

Caption

Microscopic imaging and finite element simulations the "catalytic route" electrochemiluminescence (ECL) is remarkable as long as the concentration ratio of (Ru(bpy)32+) (Ru2+) to tri-n-propylamine (TPrA) is large enough, regardless the concentration of Ru2+. The impact of this route must not be lost sight of in quantitative ECL analysis of coreactant-type analyte, because it may not only result in a nonlinear calibration curve but also favor a high analytical sensitivity in the low concentration range.
