AbstractThe absolute determination of the Cu isotope ratio in NIST SRM 3114 based on a regression mass bias correction model is performed for the first time with NIST SRM 944 Ga as the calibrant. A value of 0.4471 ± 0.0013 (2SD, n = 37) for the 65Cu/63Cu ratio was obtained with a value of +0.18 ± 0.04‰ (2SD, n = 5) for δ65Cu relative to NIST 976. The availability of the NIST SRM 3114 material, now with the absolute value of the 65Cu/63Cu ratio and a δ65Cu value relative to NIST 976 makes it suitable as a new candidate reference material for Cu isotope studies.
