Abstract

A simple method of radio gas chromatography, which avoids the necessity for an effluent gas stream splitter and a special reactor after the GLC column, has been described. The system uses the FID as a combined mass detector and combustion furnace for the conversion of14C-labelled compounds into14CO2 and operates the FID in series with the14CO2 detection system. Specific activity values of weakly14C-labelled compounds such as organic methyl esters and TMS sugars can be determined precisely with the standard error of the mean less than 3%.
