酒中成分复杂,其中甲醇、杂醇油已成为酒类卫生监测的两项重要指标。用化学法测定酒中杂醇,其操作繁琐,灵敏度和准确度都较差,各种杂醇不能单独鉴定。近年来,用气相色谱法作酒的分析时有报道,文献采用Carbowax 1500、GDX-102、Polymer No.13等作固定相进行酒的色谱分析,我们则采用邻苯二甲酸二壬酯(DNP),对色谱条件进行了探讨,并对本法的精密度和准确度进行了考核,结果满意。
Wine complex composition, of which methanol, fusel oil has become the two important indicators of alcohol hygiene monitoring. Determination of alcohol fusel alcohol by chemical method, its cumbersome operation, sensitivity and accuracy are poor, all kinds of fusel can not be identified separately. In recent years, gas chromatography for wine analysis has been reported in the literature using Carbowax 1500, GDX-102, Polymer No.13 as the stationary phase for the chromatographic analysis of wine, we use dinonyl phthalate (DNP ), Discussed the chromatographic conditions, and the accuracy and accuracy of this Law were tested, the results are satisfactory.
