Abstract
A gas-liquid chromatographic method for determining trace amounts of acrylonitrile in plastic containers and carbonated beverages using a nitrogen-sensitive detector and headspace injection technique is described. The method is suitable for the determination of acrylonitrile at concentrations down to 0.1 mg kg–1 in plastics and 0.005 mg kg–1 in beverages.
