title: Radio-gas chromatography of chromium (III) hexafluoroacetylacetonate.
abstract: A method has been developed for the determination of trace levels of chromium by radio-gas chromatography. The technique involves conversion of radioactive 51Cr to a metal chelate compound, using C2H5I131 as an internal standard, and detection of radioactivity of 51Cr in the chelate by a flow system surrounding a Nal(TI) scintillation detector. The detection limit is found to be as low as 10(-12) g. From the observed radio-chromatogram it can be shown that the method is selective and free from interference.
