Abstract
THE gas chromatographic technique of James and Martin1,2 is often used to fractionate substances biosynthesized from precursors labelled with carbon-14. For the assay of carbon-14 in the various fractions it is necessary, at present, to collect the fractions individually and then transfer them to a counting device. Direct measurement of the radioactivity of vapours as they leave the chromatographic column would save much time and labour and improve accuracy.
