Abstract
About 600 different spectroscopic samples (rods and preforms in L-113 SP carbon, AGKSP and SPK grades) were studied by spectroscopic quantitative analysis. The concentrations of impurities in parts per million were statistically compared with the visually estimated densities of the spectral lines obtained by the cathode-layer method. Concentration limits expressed as maximum concentrations in parts per million could be established for density estimations in the arbitrary scale from 0 to 3. Using the line-to-background ratio measured with the densitometer, a method was found of reporting impurities with their maximum concentration in parts per million with a confidence level of 95%.
