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...
Stable isotope analysis of Upper Tithonian limestones with dinosaur footprints from Kirmenjak quarry (Istria,Croatia)

2009/12/8
The Kirmenjak locality of western Istria, Croatia, represents the oldest evidence of a dinosaur presence on the Adriatic- Dinaridic Carbonate Platform (ADCP). In a quarry at this locality, almost a th...
Carbon and oxygen isotope analysis of leaf biomass reveals contrasting photosynthetic responses to elevated CO2 near geologic vents in Yellowstone National Park
isotope analysis leaf biomass reveals photosynthetic responses CO2 geologic vents
2010/1/19
In this study we explore the use of natural CO2 emissions in Yellowstone National Park (YNP) in Wyoming, USA to study responses of natural vegetation to elevated CO2 levels. Radiocarbon (14C) analysis...
A standard protocol for stable isotope analysis of zooplankton in aquatic food web research using mass balance correction models
stable isotope analysis zooplankton
2014/4/22
Stable isotope analysis has become a crucial tool for aquatic food web ecologists, but a lack of methodological
standardization hinders comparisons between studies. One methodological inconsistency i...
Quantifying resource partitioning in centrarchids with stable isotope analysis
centrarchids stable isotope analysis
2014/5/4
Stable isotope and gut content analyses were completed on multiple age classes of Detroit River rock bass (Ambloplites rupestris) and bluegill sunfish (Lepomis macrochirus) to determine the importance...
Seasonal changes in the importance of the source of organic matter to the diet of zooplankton in Loch Ness, as indicated by stable isotope analysis
Seasonal changes importance of the source organic matter diet of zooplankton Loch Ness stable isotope analysis
2014/6/9
Seasonal variations in the stable isotope composition (d13C and d15C) of crustacean zooplankton and their putative food sources in oligotrophic Loch Ness were recorded during 1998. Bulk particulate or...
