| Abstract: | Abstract The use of high performance liquid chromatography (HPLC) for the separation and quantitation of trace metals in solution has been hampered by the lack of A suitable detection system. The method generally used with classical metal ion separations - fraction collection and subsequent colorimetric detection - cannot easily be used in HPLC. To overcome this problem, A novel metal ion detection system based on the luminol reaction has been developed. Column effluent is successively mixed with luminol and then hydrogen peroxide before entering A chamber where chemiluminescence from the oxidation of the luminol is detected. The reaction is catalyzed by at least 20 different metal ions, and over A wide range the luminescence is proportional to metal ion concentration. The design of the system and some of its performance characteristics are described. |
