The isotopic composition of DOM and DOC can now be measured by the Thermo Scientific LC IsoLink, the on-line coupling of a liquid chromatograph with an isotope mass spectrometer. With the LC IsoLink™ interface, two approaches are possible: DOC δ13C can be measured either by direct flow injection of water samples (as well as of fractions isolated off-line from larger volumes of water) or, alternatively, for on-line separation of DOM fractions size exclusion chromatography (SEC) for instance can be applied.
