BS>The separation and deterimination of the elements mentioned in the title by chemical methods are very difficult, especially when they are present in microquantities. It is possible to separate spectral lines of the elements Ti, Nb, and Ta which are not superposed by the spectra of the accompanying elements, and which do not overlap one another. The analytical lines which can be used include: Ti--4305.92 A, Nb--2927.81 A, Ta--2933.55 A, Nb-2950.88 A, Ta--2951.9 A. The lines of U ( lambda = 4297.11) or Cr ( lambda = 4297.73 A) were used as comparative lines for TiThe Nb- and Ta-lines served as intrinsic standards. A description of the apparatus and procedure is included. (TCO)
