Description

We systematically investigate the effect of matrix on the accuracy and precision of Ba isotope measurements under different but quantified plasma conditions. A NIST SRM 3104a Ba standard solution was doped with various amounts of major matrix elements (Ca and Sr) and analysed under six different plasma conditions. The results provide an improved understanding of the matrix-induced instrumental mass fractionation and define a matrix tolerance plasma state for Ba isotope analysis. Although these experiments were performed and calibrated for Ba isotopes, they are considered to be applicable for a wide variety of isotope measurements routinely performed on MC-ICP-MS.
