High-precision measurements of water isotopes using laser absorption spectroscopy
oxygen isotopes hydrogen isotopes water laser absorption spectroscopy Off-Axis Integrated Cavity
font style='font-size:12px;'>
2017/4/11
Hydrogen and oxygen isotopic analysis using an off-axis integrated-cavity output spectroscopy (OA-ICOS) was carefully
checked for long-term stabilities, dependence on the injected water volume, inter...
The matrix effect on 238U and 232Th measurements using pressed powder pellets by LA-ICP-MS
LA-ICP-MS matrix effect U and Th

2017/4/12
Radioisotope concentrations, such as 238U and 232Th, of bulk sediments are good environmental indicators and useful
for radiometric age determinations. Pressed pellets of sediment can be analyzed by ...
Simplified technique for the measurements of Re-Os isotope by multicollector inductively coupled plasma mass spectrometry (MC-ICP-MS)
Re-Os, MC-ICP-MS, isotope measurements

2017/8/9
A method for the rapid determination of Re-Os isotopes by multi-collector inductively coupled plasma mass spectrometry (MC-ICP-MS) was developed. For Os measurements, samples were introduced into the ...
High sensitivity measurements of nitrogen isotopic ratios in coral skeletons from Palau, western Pacific: Temporal resolution and seasonal variation of nitrogen sources
coral skeleton δ15N value δ18O value δ13C value seasonal variation
