Development in electrogenerated chemiluminescence

Two novel electrogenerated chemiluminescence (ECL) methods have been developed. The electrochemical stripping chemiluminescence analysis combined the stripping voltammetry technique and flow injection chmiluminescence detection and provided the high selectivity and sensitivity. In the chmiluminescence analysis with electrogenerated reagent, the unstable reagents were on line electrochmically generated, resulting in the elimination of the instability of these reagents and emerged high activity of these palingenetic reagents. Both methods have been used for determination of some metal ions and drugs.
