Abstract

Abstract

This paper describes recent work in applying a laser ablation system (LSX-200) hyphenated with POEMSIII inductively coupled plasma mass spectrometry (LA-ICP-MS) for the in situ analysis of solid geological materials. It demonstrates the potential of LA-ICP-MS for the determination of geochemically important trace and ulra-trace elements (REE for instance) following XRF routine sample preparation. NIST SRM 612 was employed as external calibration standard and Ca as internal standard to correct for signal drift, difference in transport efficiency and sampling yield.Resultsagree well with the certified value with accuracy better than 15%, RSD less than 15% for most determined rare earth elements. LOD from 21.4×10^-9 to 231.6×10^-9 and less than 100×10^-9 for majority trace elements determined. In addition, Home-made macro function by VBA language under Excel software greatly enhanced off-line data reduction efficiency.
