“…doi:10. 1016/j.gca.2008.07.007 Zn for life, these isotope ratios have been investigated to employ them as biological indicators (Krebs et al, 1995;Helal et al, 2002) or as a marker in the medical field (Ingle et al, 2004;Ohno et al, 2005). In recent geochemical studies, variations of the 66 Zn/ 64 Zn ratio in NE Pacific seawater along a 500 m profile (Bermin et al, 2006) and in marine and continental carbonates, sulfides and Fe-Mn nodules (Marechal et al, 1999;Pichat et al, 2003) have been measured to probe and quantify paleo-environmental marine conditions.…”

“…values (Figure 4c), when using the 68 Zn + / 64 Zn + ratio for the mass bias correction, deviated from the target value of 0.00‰, independently of which acid was used for the chromatographic separation of Cu. Polyatomic ions such as 40 Ar 14 and 28 Si 40 Ar + are likely to cause interferences on 68 Zn (May and Wiedmeyer 1998, Helal et al. 2002).…”

The commonly used, but no longer available, reference materials NIST SRM 976 (Cu) and ‘JMC Lyon’ (Zn) were calibrated against the new reference materials ERM®‐AE633, ERM®‐AE647 (Cu) and IRMM‐3702 (Zn), certified for isotope amount ratios. This cross‐calibration of new with old reference materials provides a continuous and reliable comparability of already published with future Cu and Zn isotope data. The Cu isotope amount ratio of NIST SRM 976 yielded δ65/63Cu values of −0.01 ± 0.05‰ and −0.21 ± 0.05‰ relative to ERM®‐AE633 and ERM®‐AE647, respectively, and a δ66/64ZnIRMM‐3702 value of −0.29 ± 0.05‰ was determined for ‘JMC Lyon’. Furthermore, we separated Cu and Zn from five geological reference materials (BCR‐2, BHVO‐2, BIR‐1, AGV‐1 and G‐2) using a two‐step ion‐exchange chromatographic procedure. Possible isotope fractionation of Cu during chromatographic purification and introduction of resin‐ and/or matrix‐induced interferences were assessed by enriched 65Cu isotope addition. Instrumental mass bias correction for the isotope ratio determinations by MC‐ICP‐MS was performed using calibrator‐sample bracketing with internal Ni doping for Cu and a double spike approach for Zn. Our results for the five geological reference materials were in very good agreement with literature data, confirming the accuracy and applicability of our analytical protocol.

“…It is obvious that the main peak fractionated in to the five due to the isotopes of the zinc ion bearing in the tetrabenzotetraazaporphyrin ring [19]. Zinc has five stable isotopes with the mass numbers 64, 66, 67, 68 and 70, and their abundances are 48.6%, 27.9%, 4.1%, 18.8%, and 0.6%, respectively [27][28][29]. However, MS spectra of Co-Pc 7 is simpler due to, the stable isotope of cobalt is only one [30].…”
