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...
An analytical system using continuous-flow isotope ratio mass spectrometry (CF-IRMS) was developed to determine the stable chlorine isotope ratios (δ37Cl) for CH3Cl. By using appropriate devices for ...
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...
Instrumentation and methods exist for highly precise analyses of the stable-isotopic composition of organic compounds separated by GC. The general approach combines a conventional GC, a chemical reac...
Two fundamentally different approaches, termed “pointwise and “peakwise,” are currently used to correct hydrogen isotope ratio monitoring data for the presence of H3 + ion contributions. Consider...
