ジャーナル フリーIn quantitative spectrographic analysis, the normal density, D=log (opacity) as measured quantity, has been most widely used, but recently so-called Seidel-density, W=log (opacity-1), or so-called P-density, P= (D+W) /2 has often been used. But it has not been evidently confirmed that in which case the density W or P should be used, and in which points W or P is more favourable than the normal density. The author has made a theoretical study on the working-curve of the internal-standard method and compared the working-curve in Seidelscale with that in the normal-scale from the point of view of the errors.
The results of this study are summarized as follows:
1. The slope of working curve in Seidel-scale is steeper than that in normal scale.
2. In practical concentration range, errors are sufficiently eliminated in the internal standard method, using the normal scale, but in this range it does not necessarily follow that the errors is sufficiently eliminated in Seidel-scale.
3. In low concentration range sometimes Seidel-scale is more favourable but sometimes is not. Generally speaking, Seidel-scale is more favourable in case of the slope of working curve in this scale, being extremely steeper than that in normal scale.抄録全体を表示PDF形式でダウンロード (760K) -

ジャーナル フリー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.抄録全体を表示PDF形式でダウンロード (715K) -

ジャーナル フリーA Wadsworth Littrow type infrared spectrometer using a galvanometer has been built. Prism is a sodium chloride of surace area IIX 8cm and angle 65°. Detector is the thermo-couple which has a long time constant and sensitivity of 3 μV/μW at 760 mmHg.
Wave length of recording spectrum is linear, and slit is automatically opened by a slit cam. As the sensitivity of a galvanometer is 5×10-8 volt, slit must be considerably wide, so the resolution of the spectrometer is not good, nevertheless the 10μ band of ammonia was detected distinctly.抄録全体を表示PDF形式でダウンロード (600K) -

ジャーナル フリーIn previous year, a Wadsworth Littrow type infrared spectrometer using a galvanometer was built, In the spectrometer, a prism was set at minimum deviation, the prism and Wads-worth mirror were rotated simultaneously. In this time, a Littrow type spectrometer which is not a minimum deviation type has been built, and its resolution power has been examined theoretically and experimentally.抄録全体を表示PDF形式でダウンロード (3960K) -
