X-ray spectrographic analysis at low two-theta angles [electronic resource] / Dorothy J. Reed, Mineral Sciences Division. Ottawa : Queen's Printer, 1970. p. 49-51 : charts Reprint series ; RS 96 Cover title. "Reprinted from the Canadian Spectroscopy, vol. 15, issue no. 2, March 1970, pages 49-51 inclusive." Historical publication digitized from print 2017 [by Natural Resources Canada]. Includes bibliographical references. "Undifferentiated radiation has been removed from the continuum at low two-theta angles by inserting a lead shield at the end of the receiving collimator to remove the upper third of the collimated X-ray beam before it strikes the analyzing crystal. The removal of this radiation caused no decrease in analytical sensitivity although counting rates were reduced. Results are presented for the determination of tungsten and hafnium in steels and tantalum in high temperature alloys"--Abstract, p. 49.
