Effects of different cone combinations on accurate and precise determination of Li isotopic composition by MC-ICP-MS

Accuracy and precision (2 s.d. derived from triple analysis) of Li isotopic ratios of Certified Standard L-SVEC determined by MC-ICP-MS using different cone combinations. Shaded areas are combined measurement uncertainty [uc (δ7Li)] for each cone combination. The Standard + X combination is recommended here to obtain accurate and precise Li isotope ratios.115
