Calibration-Free Analysis of Li Isotope Ratios Using Laser Ablation and Laser Absorption Spectroscopy
Abstract
Li ratios demonstrates relative isotopic precisions of 0.6-1.8% for spectra acquired in 30 s. Isotope ratios determined from the spectral fits show relative accuracy within -0.3% to -5% of ICP-MS measurements, without requiring calibration to external standards, and offering a rapid analysis approach to lithium isotope determination in solid materials relevant to nuclear energy, safeguards, and geochemistry.
