Abstract
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.
摘要
借助二维气相色谱法并应用现场气相色谱技术，可以分离和检测葡萄酒中的单乙二醇（MEG）和二甘醇（DEG）。样品经过处理（“盐析”）后，MEG的指示值为10毫克/升，DEG为1毫克/升。通过气相色谱-质谱联用可检测出微量成分。
