A Laser Ablation System for Solid Sample Analysis by ICP-AES
Journal of Analytical Atomic Spectrometry
(1989)
Abstract
A laser ablation sample introduction system, based on a Nd : YAG laser with an X-Y-Zdirectional sampling
head, has been designed and constructed for use with inductively coupled plasma optical emission
spectrometry. A study has been made of a number of parameters which affect the performance of the system
to establish the optimum operating conditions. South African Reference Material (SARM) rock samples have
been analysed using the system, and the results obtained have been compared with the certificate values. The
importance of using closely matrix-matched samples and standards is demonstrated. Precision studies on
SARM 5 (pyroxenite) show that both intra- and inter-sample precisions are typically 10% (relative standard
deviation ).
