U–Pb dating of CA/non-CA treated zircons obtained by LA-ICP-MS and CA-TIMS techniques: impact for their geological interpretation
Chemical Abrasion Isotope-Dilution Thermal Ionization Mass Spectrometry (CA-ID-TIMS) is known as a high precision technique for resolving lead loss and improving the interpretation of U–Pb zircon age data.
Comparison of 795 nm and 265 nm femtosecond and 193 nm nanosecond laser ablation inductively coupled plasma mass spectrometry for the quantitative multi-element analysis of glass materials
A benchmark of FUV-ns- vs. NIR/MUV-fs-LA-ICPMS of glass materials concerning the accuracy of analysis is reported.
Development and characterization of custom-engineered and compacted nanoparticles as calibration materials for quantification using LA-ICP-MS
Flame spray synthesis was used to produce a reference nano-material with a customized composition for use in LA-ICP-MS.
Evaluation of pneumatic nebulization and ns-laser ablation ICP-MS for bulk elemental analysis and 2-dimensional element mapping of iron meteorites
In this work, the capabilities and limitations of ns-LA-ICP-MS for bulk and spatially resolved (elemental mapping) analysis of iron meteorites were assessed.

A new method produces undiluted pressed powder tablets for LA-ICP-MS opening prospects for manufacturing mineral standards for isotopic and geochemical analysis.
LA-ICP-MS Pb–U dating of young zircons from the Kos–Nisyros volcanic centre, SE Aegean arc
Dating of zircons in the 100 ka range is possible with LA-ICP-MS applying Th-disequilibrium correction.
Optimisation of laser parameters for the analysis of sulphur isotopes in sulphide minerals by laser ablation ICP-MS
The effects of laser type (Nd:YAG and excimer lasers) and their analytical parameters on 34S/32S isotopic fractionation during LA-ICP-MS analysis were investigated.
Fractionation of sulphur relative to iron during laser ablation-ICP-MS analyses of sulphide minerals: implications for quantification
In this study we investigate the effect that the mineral composition has on the quantification of sulphur by Laser Ablation ICP-MS (LA-ICP-MS) between a range of sulphide minerals: pyrite, pyrrhotite, bornite, chalcopyrite, sphalerite, pentlandite and tetrahedrite.
What happens when n= 1000? Creating large-n geochronological datasets with LA-ICP-MS for geologic investigations
LA-MC-ICP-MS and LA-SC-ICP-MS were used to generate large n (i.e., n = 1000) U–Pb detrital zircon age data sets with little sacrifice of precision and accuracy over more traditional methods.
In situ U–Pb dating of bastnaesite by LA-ICP-MS
Bastnaesite, a common accessory mineral in REE ore deposits, is ideal for U–Pb isotopic dating because of its relatively high U and Th contents.
The zircon ‘matrix effect’: evidence for an ablation rate control on the accuracy of U–Pb age determinations by LA-ICP-MS
This papers describes the source of systematic bias in U–Pb zircon dating by LA-ICP-MS.
