A Preliminary Study to Determine the Hydrogen and Oxygen Isotopic Compositions of Natural and Bottled Water using High Sensitivity Isotope Ratio Mass Spectrometry [PDF]
In this study, we introduce the stable isotopic results of water using a recently installed high sensitivity isotope ratio mass spectrometry (HS-IRMS) system at the Korea Institute of Geoscience and Mineral Resources (KIGAM).

Stable Isotope Ratios and Forensic Analysis of Microorganisms [PDF]
ABSTRACTIn the aftermath of the anthrax letters of 2001, researchers have been exploring various analytical signatures for the purpose of characterizing the production environment of microorganisms. One such signature is stable isotope ratios, which in heterotrophs, are a function of nutrient and water sources. Here we discuss the use of stable isotope

Stable Sr isotope (88Sr/86Sr) fractionation in calcite precious corals
Stable isotope ratios of Sr (88Sr/86Sr) are a novel indicator for identifying terrestrial and oceanic Sr cycling and biological processes. Here we evaluate the temperature dependence of stable Sr isotope ratios (δ88Sr) in the calcite skeletons of ...

Equations for lipid normalization of carbon stable isotope ratios in aquatic bird eggs. [PDF]
Stable isotope ratios are biogeochemical tracers that can be used to determine the source of nutrients and contaminants in avian eggs. However, the interpretation of stable carbon ratios in lipid-rich eggs is complicated because (13)C is depleted in ...

To broaden the range of measurable pesticides for stable isotope analysis (SIA), we tested whether SIA of the anthranilic diamides cyantraniliprole (CYN) and chlorantraniliprole (CHL) can be achieved under elemental analyzer/isotope ratio mass ...

Tracing sheep binary C3–C4 diet using stable isotope ratio (δ13C)
Stable isotopes are an important tool to assess livestock diet in binary mixtures of C3-C4 forages. However, the use of stable isotopes to trace livestock diet using tropical arboreal legumes has been limited.

The association between carbon and nitrogen stable isotope ratios of human hair and hypertension
Background The relationship between stable isotope ratios and dietary protein sources has been reported. However, few studies have examined the effect of stable isotope ratios on metabolic risk in humans. We investigated whether the stable isotope ratios
