Abstract
Isotope ratio mass spectrometry is effected by: injecting a sample for analysis into a gas chromatography column; directing an effluent from the gas chromatography column to a switching arrangement; and selecting a configuration of the switching arrangement, such that: in a first mode, the effluent from the gas chromatography column is provided as an input to a peak broadener; and in a second mode, an effluent from the peak broadener is provided to a mass spectrometer for isotope ratio mass spectrometry without the effluent from the gas chromatography column being provided as an input to the peak broadener.
