Abstract
The direct introduction of solid samples into an inductively coupled plasma (ICP) has been studied using ablation of metals by a focused XeCl excimer laser. The laser pulses form a very energetic microplasma at the metal surface from which the ablated species are carried into a stream of argon and are detected using a gated integrator/boxcar averager. This method is applied to the analysis of Ni and Cr in stainless steels.
