Abstract
AN efficient device for trapping materials from the effluent of a gas chromatography column has been developed which facilitates collection of components labelled with carbon-14 in close proximity to an efficient scintillator. Collection of components from aliquot s of carrier gas into separate traps for subsequent counting affords a sensitivity of carbon-14 assay limited only by the high 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.
