Analysing Sr isotopes in low Sr samples such as single insects with ICP-MS/MS using N2 O as a reaction gas for in-line Rb separation.
CONCLUSIONS: A minimum of 5 mg of insect tissue is required for Sr isotope analysis. This new ICP-MS/MS method enables Sr isotope analysis in single insects, allowing population-scale studies to be feasible and applications with time-critical uses such as biosecurity possible.
