Zur Spektralanalyse des Bors im Eisenh�ttenlaboratorium

Ferrous metallurgy

“…Available spectral lines for the spectrometric determination of boron in steel were evaluated (210); the spectrographic methods developed included the use of a vacuum spectrograph (125), a carbon monoxide atmosphere (449), a hollow cathode discharge (443), a solution technique (128), and a carrier distillation technique (441)• One spectrographic point-to-plane technique stresses electrode shape and polarity (204•), and another uses a high dispersion spectrograph to separate the B 2497.73-1. line from Fe 2497.72 A (263). A spark source mass spectrographic method was also developed trace amounts of boron in steels (17,91,166) and stainless steels (36).…”
