Thc application of inducdvely coupled plasma atomic-

fluoreictnce spectrometry offers a possible solution to the
limitations of conventional flames for atomic emissionr

sPectral interference encountered with
inductively coupled plasma-emission sPcctrometry.

Results have been published whiqh show satisfactory
performance for the analysis of alloyed steel standards.
However, the performance ofthe instrumen! when used
I
in routinc analysis has yct to be evaluated.
