Laser Ablation-assisted Radiofrequency Atomization Excitation Source for Direct Determinations of Elements in Ceramics

Abstract

A radiofrequency He discharge atomization/excitation source which was assisted by laser ablation was developed for the direct elemental analysis of ceramics by atomic emission spectrometry. Effects of laser irradiation, such as sensitivity enhancement and alleviation of matrix effects, were found in the direct atomization/excitation of ceramics. Calibration using powder reference materials became feasible for sintered ceramic samples.
