摘要
采用电导检测模式,对葡萄中的6种有机酸成分进行分离测定。将葡萄样品通过洗涤、浸提、过滤之后进样,可以测定其丙酸、丁酸、乳酸、乙酸、柠檬酸、酒石酸6种有机酸,在一定的色谱条件下,6种离子都具有很好的线性和较低的检出限。采用抑制电导的离子色谱法是分析葡萄中有机酸成分的高效、准确的方法。
In this paper, a method for simultaneous determination of six kinds of organic acids in grapes was proposed. The organic acids including monoprop, butyric acid, lactic acid, acetic acid, citric acid, tartaric acid, lactic acid were analyzed by means of ion chromatography using a gradient elution. The results showed the reliability of the IC method. Under favorable chromatographic conditions, good linear relationship, sensitivity and reproducibility were obtained.
