Isotopic reference materials are crucial to isotopic measurement, and isotopic compositions of reference materials constitute basic parameters for isotopic measurement. This paper deals with the new reference material with basaltic matrix for Ti isotope measurement. The preparation of the reference material strictly followed the relevant metrological technical standard stipulated by the state, which included homogeneity and stability tests and certification analyses. The certified values and uncertainty at the 95% confidence level were δ⁴⁷Ti(‰)=-0.53±0.07, δ⁴⁸Ti(‰)=-1.05±0.09, δ⁴⁹Ti(‰)=-1.57±0.16 and δ⁵⁰Ti(‰)=-2.10±0.18. This newly certified reference material can be used for assessment of isotope fractionation during chemical separation of geological samples instrumental calibration in Ti isotope measurements, and data quality evaluation in the whole process of sample preparation and isotope measurement.
