Abstract: With the wide application of MC-ICP-MS, analytical methods for metal stable isotopes have been tremendously improved. Therefore, the metal stable isotope geochemistry has become a new field of earth sciences. Taking V and Ba isotopes as examples, this paper has reviewed recent progresses of analytical techniques of metal stable isotopes, especially introduced the high precision analytical methods, for analyzing V isotope [with a long term external precision of δ51 VAA better than ±0.1‰ (2SD)] and Ba isotope with SRM3104a as basic reference material (with a long term external precision of δ137/134 BaSRM3104a better than ±0.05‰ (2SD)), newly established by the Metal Stable Isotope Laboratory of the China University of Science and Technology.

Keywords: V isotope Ba isotope MC-ICP-MS analytical method
