Contrasting particle size distributions and Fe isotope fractionations during nanosecond and femtosecond laser ablation of Fe minerals: Implications for LA-MC-ICP-MS analysis of stable isotopes
The first offline comparison of ns- and fs-laser for Fe isotope analysis. Ablation produced particle size distribution and morphology were studied. Laser ablation induced isotopic fractionation was quantified and investigated. Isotopically non-stoichiometric sampling was found for ns-laser ablation. Ablation is largely independent of samples and laser conditions for fs-laser.
