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.magnified image
