The application of a wide-slot nitrous oxide-nitrogen-acetylene burner for the atomic-absorption spectrophotometric determination of aluminium, arsenic and tin in steels by the single-pulse nebulisation technique

Abstract

Single-pulse nebulisation of 10 per cent. m/V iron or steel solutions into a nitrogen-diluted nitrous oxide-acetylene flame maintained on a specially designed wide-slot burner is a useful technique for the determination of tin, arsenic and soluble aluminium in iron and steels. Use of this method avoids the need for prior separation of the analyte. A deuterium lamp was found to be unsatisfactory for measuring the background (non-specific) absorption when determining aluminium and tin, the explanation for which is postulated.
