比較法に於けるスペクトル線の写真黒度及び誤差

II: 実験Seidel黒度による鉄鋼中の微量元素の定量分光分析

抄録

In order to examine the results of the theoretical study in the first report, the author, applying Seidel-scale, has made an experimental study on the quantitative spectrographic analysis of elements in steels at low concentration. The results of this study are summarized as follows.
1. In low concentration range sometimes calibration by Seidel-scale is more favourable but sometimes is not. Calibration by Seidel-scale is more favourable when the slope of the working curve in this scale is extremely steeper than in normal scale.
2. It has been experimentally confirmed that the results of theoretical study is right.
3. In the analysis of low concentration, the application of high energy source is rather preferable than the application of Seidel-scale.
