Investigation of potentialities of atomic fluorescence spectrometry with a tantalum coil atomizer for gas monitoring

Abstract

The analytical potential of a non-dispersive atomic fluorescence spectrometer with a tantalum coil atomizer for gas monitoring are investigated. The analytical procedure for the determination of iron in argon, introduced as iron pentacarbonyl, is suggested as a first step of reactive gas monitoring. Parameters optimized include the atomization temperature and duration time and the atom residence time in the atomizer. These parameters are optimized by varying the charge voltage and condenser capacity. The detection limit achieved for iron is 4 ng l^–1 of gas. The relative standard deviation s_r= 0.03.
