- 論文の詳細を見る
A spectrometric determination of nitrogen in steel was performed with d.c. arc excitation in the vacuum ultraviolet region. Two nitrogen spectral lines, 1, 742 A and 1, 745 A, were utilized for the determination of nitrogen using CI 1, 930 A as internal standard in the wave-length region of 1, 200-2, 000 A. In argon atmosphere (700 mm Hg, 28 A arc current) and in helium atmosphere (700 mm Hg, 30 A arc current) nitrogen could be determined belew 50 ppm after a pre-arcing time of 100 sec. Better reproducibility could be obtained with the line 1, 745 A rather than with 1, 742 A.
