The gas chromatographic elution behaviour is reported for a total of 16 vanadium(111) and oxovanadium(1V) fluorinated β-diketonates on a column consisting of a lightly loaded, non-polar stationary phase and diatomite support. The superiority of the vanadium(111) chelates is shown to include electron-capture detection. Detection limits of 14 chelates are given for the flame ionization detector. Separation of the two oxidation states of a metal by gas-liquid chromatography is demonstrated for the first time.
