A new premixed chemical burner for emission and absorption spectroscopy with separated fuel and sample introduction

Abstract

A new version of the Babington nebulizer is described where dry aerosols from solutions and powder samples can be introduced into air-acetylene and nitrous oxide-acetylene flames, as well as ICP torches. A special burner is described in which the premixed burner gases are completely separated from the sample introduction into the flame plasma. The powder samples could also be successfully introduced into a 9.2 MHz high power ICP, as well as 28 and 50 MHz low power ICP sources. The investigations show that a powder leaf sample behaves similarly to an aqueous solution in the plasmas of a nitrous oxide-acetylene flame and the ICP sources. © 1983.
