摘要: The analytical procedure for the determination of Ba and rare earth elements in rocks minerals by ICP-MS is described. yield mono-oxide hydroxide ions elements, chloride has been determined. A Microsoft Excel spreadsheet template written to calculate expected peak intensities all possible analyte species (M+, MO+, MOH+ MCl+) as a function mass number. degree interferences different isotopes estimated interferent equivalent concentrations are given which no isotope free from available. method applied analysis four Geo-Reference samples AC-E, GSP-1, G-2 AGV-1; accuracy better than ±10% most when compared with recommended reference values.
