In-situ chromium isotope measurement of chromium-rich fine grains in the Murchison CM2 chondrite
54-chromium isotopic anomaly presolar grain
2017/4/12
Isotopic anomalies of 54Cr have been reported in bulk chondrites. Stepwise dissolution experiments have suggested
the presence of a carrier of the 54Cr anomaly, probably of presolar origin. Although ...
Measurement of chlorine stable isotopic composition by negative thermal ionization mass spectrometry using total evaporation technique
chlorine stable isotopes total evaporation method negative thermal ionization mass spectrometry small samples
2017/8/9
A total evaporation negative thermal ionization mass spectrometry (TE-N-TIMS) technique for the isotopic analysis of chlorine was developed. This technique provides fast and reliable way to determine ...
New sequential separation procedure for Sr, Nd and Pb isotope ratio measurement in geological material using MC-ICP-MS and TIMS
Sr Nd isotope ratio MC-ICP-MS TIMS
2017/8/10
A new 3-step sequential separation chemistry for Sr, Nd and Pb from silicate samples, which is suitable for isotope analysis by MC-ICP-MS as well as TIMS, has been developed. The chemistry is designed...
