Quantitative Analysis of Trace Elements in Geological Materials by Laser Ablation Icpms: Instrumental Operating Conditions and Calibration Values of Nist Glasses

Abstract: A UV laser ablation microprobe coupled to an ICPMS has been used to determine trace element concentrations in solids with a spatial resolution of S O microns and detection limits ranging from 52 pg/g for Ni to S O ng/g fortheREE,Th,andU.Experimentsdesignedtooptimize laser operating conditions show that pulse rates of 4 Hz p d u c e a steady state signal with less inter-element fractionation per unit time than higher pulse rates (10-20 Hz). Comparisons of laser microprobe analyses of garnets and pyroxenes using… Show more

“…This indicates that the oxide interference on the REE is minimized in laser ablation mode even with JB-1a and JG-1a, except for extremely enriched rock sample in light REE, as pointed out by several previous studies (e.g., Jackson et al, 1992;Norman et al, 1996). Thus, we have carried out all measurements at 1.0 to 1.2 cm sampling length.…”

“…Inductively coupled plasma mass spectrometry coupled with a laser ablation technique (LA-ICP-MS) and secondary ion mass spectrometry (SIMS) are now accepted as precise direct and rapid sensitive analytical tool for trace element components for geological mineral or glass inclusions (e.g., Bea, 1996;Jackson et al, 1992;Hinton and Upton, 1991;Meston et al, 1984;Nesbitt et al, 1997;Norman et al, 1996;Shimizu and Richardson, 1987;Yurimoto et al, 1989). Presently, one of the basic petrological description requires determination of major and trace element abundance as whole rock composition, as well as rock type classification and analysis of mineral modal compo-used.…”
