RADIOASSAY BY GAS CHROMATOGRAPHY OF COMPOUNDS LABELLED WITH CARBON-14
An efficient device is described for trapping materials from the effluent of a gas chromatographic column which facilitates collection of components labeled with carbon-14 in close proximity to an efficient scintillator. Collection of components from aliquots of carrier gas into separate traps for subsequent counting affords a sensitivity of carbon-14 assay limited only by the sensitivity of liquid scintillation counting technique. Continuous scintillation counting of a single trap through which the column effluent flows permits the high resolution and convenience afforded by simultaneously recording component elution and radioactivity. Applications are described in the radioassay of fatty acid esters. (C.H.)
