Comparison of water isotope analysis between cavity ring-down spectroscopy and isotope ratio mass spectrometry
oxygen isotopes hydrogen isotopes water isotope ratio mass spectrometry (IRMS) cavity ring-down spectroscopy (CRDS)
2017/4/10
δD and δ18O of natural waters with δ18O ranging from –24 to –6‰ were measured using a cavity ring-down spectroscopy
(CRDS) in order to confirm that the CRDS method can be an alternative to convention...
Tin isotope analysis of cassiterites from Southeastern and Eastern Asia
MC-ICP-MS tin isotopic variation cassiterite hydroiodic acid
2017/4/11
An analytical technique is presented for isotope analysis of a Sn ore mineral, cassiterite. Hydroiodic acid was used to
successfully decompose the cassiterite samples. An extraction chromatographic m...
New supplemental activator for lead isotope analysis using TIMS
Pb isotope activator TIMS colloidal silica germanium
2017/4/12
We have devised a new supplementary activator for lead isotope measurements performed using thermal ionization
mass spectrometry (TIMS). The activator consisted of a mixture of 250 ppm Ge and 500 ppm...
