Use of a continuous source of excitation, an argon-hydrogen-air flame. and an extended flame cell for atomic absorption flame spectrophotometry

Abstract

A continuous source of excitation in conjunction with an argon-hydrogen-entrained air flame, an extended flame cell, a medium-dispersion monochromator and a typical detection system is shown to give good sensitivities for the atomic absorption flame spectrophotometric measurement of 21 elements. Useful working curves over a 100-fold concentration range are obtained for each of the 21 elements using the simple experimental system. The advantages gained with this system are discussed. © 1967.
