Determination of Trace Elements in Cassiterite by Laser Ablation-ICP-MS

Abstract: A method for determination of trace elements in cassiterite by 213 nm laser ablation inductively coupled plasma mass spectrometry with lithium tetraborate flux sample preparation procedure and in-situ focusing has been investigated. The relative deviations of measurement from flux sample preparation procedure and in-situ focusing are less 25% and 10%－120%, respectively.
