[Determination of mono- and diethylene glycol in wine by two-dimensional gas chromatography]

By the aid of two-dimensional gaschromatography and the application of the live-GC-technic monoethylenglycol (MEG) and diethylenglycol (DEG) from wine can be separated and detected. After the treatment of samples ("Salting-out") the indication value for MEG is 10 mg/l and 1 mg/l for DEG. The security of small quantities occurs with GC-MS-coupling.
