Recent Results with a Nitrous Oxide—Acetylene Burner in Atomic-Absorption Flame Photometry

Abstract

Performance data are presented for several elements determined by atomic-absorption flame photometry with the use of a high sensitivity nitrous oxide—acetylene burner. Utilizing the specific advantages of this flame, the effect of gas mixtures, feeding rate, and the height of reaction zone on the sensitivities achieved are presented. Flame profiles of several elements studied will be discussed with emphasis on using multiple-pass optics for increased sensitivities. Information will be presented on the problems of this type of flame. Results are presented in terms of the precision and accuracy of routine determinations under selected optimum system conditions and will be discussed.
