Abstract

The quantitative possibilities of visual spectroscopic analysis with the Spectranal have been investigated. A multiple-line standard technique, with the Platinum electrode spectrum as the standard, was devised for simultaneous determination of relative concentration of several elements normally found in the ash of compounded rubber. An accuracy of better than plus or minus 20% of the amount present was achieved. The procedure will be practical wherever convenience, speed and sensitivity of analysis are of greater importance than absolute accuracy.
