Multimedia distributions, bioaccumulation, and trophic transfer of microcystins in the Geum River Estuary, Korea: Application of compound-specific isotope analysis of amino acids [PDF]
To determine distributions, bioaccumulation, and trophic transfer of freshwater cyanobacterial toxins such as microcystins (MCs), surface water, suspended solids, sediments, and coastal organisms were collected from seven stations in inner and outer ...

An analytical system for stable isotope analysis on carbon monoxide using continuous-flow isotope-ratio mass spectrometry [PDF]
A fully automated system for the determination of δ13C and δ18O in atmospheric CO has been developed. CO is extracted from an air sample and converted into carbon dioxide (CO2) using the Schütze reagent.

Stable Carbon Isotope Ratio (δ13C) Measurement of Graphite Using EA-IRMS System
δ13C values in non-irradiated natural graphite were measured. The measurements were carried out using an elemental analyzer combined with stable isotope ratio mass spectrometer (EA-IRMS). The samples were prepared with ground and non-ground graphite, the
