High-Precision D/H Measurement from Organic Mixtures by Gas Chromatography Continuous-Flow Isotope Ratio Mass Spectrometry Using a Palladium Filter Herbert J. Tobias and J. Thomas Brenna*
Division of Nutritional Sciences, Cornell University, Ithaca, New York 14853
Continuous-flow high-precision determination of D/H ratios from an organic mixture is described using gas chromatography coupled to a Pd filter system as an interface for isotope ratio mass spectrometry. A gas chromatograph and combustion and reduction furnaces are connected to a Pd filter via a postcolumn head pressure makeup gas to increase chromatographic sensitivity. This interface is evaluated using benzene as an internal standard in a mixture of ethylbenzene and cyclohexanone in hexane with analyte quantities of
