The determination of sulphur and phosphorus by cool-flame chemiluminescence emission spectrometry with an electrothermal atomiser for sample introduction

The technique described allows simple and rapid determination of sulphur and phosphorus in solutions of samples and sample digests. A graphite-tube atomisation device is employed for the introduction of microlitre volumes of liquid samples, after desolvation, into a cool argon—hydrogen entrained air flame in which the chemiluminescent emission from S₂ and HPO species is monitored by using a wide band-pass monochromator system.
