Accurate Determination of Lithium Isotopic Compositions in Geological Samples by Multi-collector Inductively Coupled Plasma-Mass Spectrometry

This study established a simple and efficient method for the separation of Li from different types of geological samples (water and rock) and an accurate measurement of Li isotopic compositions. The external precision (2σ) of this technique, determined by repeated measurement of pure Li standard solutions and seawater was < ±0.8‰. Experimental results showed significant Li isotopic fractionation during leaching process, and this deviation can be avoided by recovering Li completely.
