建立了果酒中5种常见有机酸的离子色谱检测方法,使用戴安ICS1500离子色谱配合淋洗液梯度洗脱使酒石酸、苹果酸、柠檬酸、抗坏血酸(Vc)、乳酸5种有机酸完全分离。结果表明,各组分RSD小于1%,回收率为91%～98%。

An ion chromatographic method for the detection of five organic acids in fruit wine was developed by using DIONEX ICS-1500 ion chromatography combining with gradient elution.Tartaric acid,malic acid,citric acid,antiscorbic acid and lactic acid were separated completely.The results show that the RSDs of various components are smaller than 1%,and the recovery rates are within the range of 91%~98%.The pretreatment of this method is simple,the recovery rate is high and the determination result is satisfying.
