title: A quantitative universal detection system for organic compounds in gas chromatography with isotopically enriched (13)CO2.
abstract: Cheap and cheerful: Postcolumn carbon-isotope dilution with (13)CO(2) in combination with the coupling of gas chromatography, combustion, and EIMS (valve in position B in the picture) provides a generic quantitative approach for every organic compound without the need for specific standards. A GC-MS instrument can be upgraded by a simple low-cost modification without any loss of the structural information provided by electron ionization sources.
