| Abstract: | A tubular platinum electrode packed with small chips of platinum is described which was shown to function with 100% electrolytic efficiency. Application of the electrode is described for the coulometric determination of electroactive species in the effluent from a liquid chromatograph. Cu and Fe were determined in a series of standards. An average relative deviation of less than 2 ppt was obtained for analysis of samples containing 5 mug of Cu(II) and 5 mug of Fe(III). |
