“…Both reagents are known to produce strong CL using a portfolio of oxidants and in the presence of many analytes. However, Ru(phen) 3 2+ is utilized to a much lesser extent than Ru(bpy) 3 2+ as CL reagent in chemical analysis, despite the fact that in many applications it was found to be of an equivalent or higher CL efficiency compared to Ru(bpy) 3 2+ (14,(17)(18)(19)(20). Methods for the assay of barbituric acid in synthetic samples, enoxacin and isoniazid were developed using Ru(phen) 3 2+ and very low detection limits were obtained (18,19,21).…”
