Validation of digestion and element separation methods and a new data reduction program (IsotopeHf®) for Lu-Hf isotope dilution analysis by MC-ICP-MS

open access: yesRevista Mexicana de Ciencias Geológicas, 2017
The Lu-Hf isotope system is not only an important geochrono- meter but also a powerful tool for petrogenetic studies. To determine reliable analytical results of this system from rock and mineral samples, a protocol is established that includes ...

Automatic Purification of Li Isotopes from Geological Samples by High-Pressure Ion Chromatography

open access: yesYankuang ceshi
High-quality purification of lithium (Li) is crucial in measuring 7Li/6Li ratios of whole rocks precisely by MC-ICP-MS. Many scholars have proposed traditional manual Li purification methods by cross-combining the types of eluents, types of resin, resin ...

High spatial resolution analysis of Pb and U isotopes for geochronology by laser ablation multi-collector inductively coupled plasma mass spectrometry (LA-MC-ICP-MS)

open access: yesAnais da Academia Brasileira de Ciências, 2009
Age determinations using the 235U and 238U radioactive decay series to the daughter isotopes 207Pb and 206Pb, respectively, using the mineral zircon (ZrSiO4), are widely used to decipher geological processes.
