Abstract

Differences in copper line intensities depending on changes in minor impurity contents of anode copper have been observed. A statistical investigation of this phenomenon has been made. The base for this statistical investigation is 400 plates and corresponding analytical records from our routine spectrochemical work. For the excitation condition used, namely an interrupted arc, a regression equation for the depending of copper line intensity on impurity amounts has been calculated according to the method of least squares.
