Validation of Trace Element Analysis of Geological Materials by Single-Pulse Laser Ablation-Inductively Coupled Plasma-Mass Spectrometry (LA-ICP-MS)

Laser ablation–inductively coupled plasma – mass spectrometry (LA–ICP–MS) is a powerful tool for determining the elemental and isotopic compositions of various samples. The disadvantage LA–ICP–MS that it consumes more sample material than other types in situ analytical methods. To extend application this method to trace element analysis, we conducted single-pulse analysis Reference Materials National Institute Standards Technology (SRM 610, 612, 614) United States Geological Survey (BCR-2G, BHVO-2G, BIR-1G). accuracy determined concentrations precision were verified by comparison with recommended these standards those obtained conventional same system. Time-resolved profiles analyzed elements glass samples show background-corrected intensity reaches peak immediately after start laser pulse then gradually decreases. During each isotope ratios are stable until 5% values. relative standard deviation analyses significantly higher analysis. However, most from reference materials except NIST SRM614, SRM612, BCR-2G, BHVO-2G mostly agreed values within 20%. In addition, geochemical features basaltic glasses accurately reproduced analyses. conclusion, provides usable results determination multiple geological materials.
