| The Application of Multiple-Collector Inductively Coupled Plasma Source Mass Spectrometry to the Determination of Cu Isotope Variation |
| A method for analyzing Cu isotope compositions using multiple-collector inductively coupled plasma source mass spectrometry is presented in this paper. The instrumental mass fractionation is corrected using a "sample-standard bracketing" technique. The research includes①the assessment of isobaric interference and effects of Cu concentration, and②the repeatability of 65Cu/63Cu ratio measurements. |
