Paper Abstract

Elemental analysis of solids using the inductively coupled plasma (ICP) often involves the time-consuming step of reducing the solid to a solution that is nebulized into the plasma. Most of the sample preparation step can be eliminated by introducing the solid directly into the ICP using a laser ablation technique. This report describes the main results of a study of laser ablation using an acousto-optically Q-switched Nd:YAG laser. The laser pulses (5 kHz rep. rate) were focused on a solid metal surface to generate a metal aerosol which was entrained in a flowing gas stream, transported through a tube, and then introduced directly into the ICP. Some characteristics of laser ablation for solid steel analysis are reported along with calibration curves and the accuracy and precision of the method for several elements.
