Abstrakt: Summary A gas chromatographic method for the quantitative determination of diethylene glycol in wine, red and white grape juice, and red and white grape juice concentrates is described. The method includes continuous extraction of the diethylene glycol with ethyl acetate by the aid of a rotation perforator. Using the new generation of chemically bonded stationary phases on fused silica together with an appropriate modern cold on-column injection system coupled with an autoanalyzer and a retention gap, the GLC analysis is shown to provide adequate information for quality control purposes.
