We proposed to combine an ultra-micro flowanalysis instrument using the fused-silica capillary and the CL detector.The CL reaction of luminol and hydrogen peroxide was adopted and thebatch-type CL detection cell was used. Luminol and isoluminol-labeledprotein as a model were sensitively and reproducibly detected with verysmall amounts of quantitative reagents. The analyses were repeated atleast 100 times without any treatments such as washing capillaries orexchanging the hydrogen peroxide solution. The present system successfullypromoted the miniaturization, simplification, and sensitization of theanalytical system.
