Laser Ablation for the Introduction of Solid Metals into an Inductively Coupled Plasma

摘要

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.
