Thermo Fisher Scientific has developed an ion chromatography (IC)-based method to simultaneously determine lithium, sodium, and calcium in lithium carbonate without handling hazardous reagents.
Application Note 1090: IC Assay for Lithium, Sodium, and Calcium in Lithium Carbonatedemonstrates accurate determinations of these three analytes by separation on a cation-exchange column and detection by suppressed conductivity. This approach offers a fast (25 minutes), simple, accurate, and robust alternative to the time-consuming assays for these three analytes in the current United States Pharmacopeia (USP) monograph...
