抄録

The authors pointed out, in the 6th report, that the various physical properties of carbon electrode affect the sensitivity and precision of this spectrochemical method for trace impurities in zinc. In this report, the authors describe the physical properties of carbon electrodes purchased from domestic producers, since 1950. From these results and repeated routine spectrochemical analysis, the influence of the physical properties on the analytical sensitivity and precision was determined and a sampling inspection system was established to find out the optimum lot of carbon electrodes (absorption of sample solution\doteqdot170 mg, Shore hardness\doteqdot30) for spectrochemical analysis of zinc.
