摘　　要：介绍了一种简单的离子色谱方法,用来直接检测液态食品中的安息香酸盐。采用全新的ICS-3000型多功能离子色谱仪,淋洗液自动发生装置在线产生氢氧化钾淋洗液,配合高容量的IonPac AS18色谱柱使用,对标准溶液和多种基体的实际样品进行了检测。样品只需要进行稀释和超声脱气即可直接进样,具有操作方便、重现性好、灵敏度高等特点,用于实际样品的检测,加标回收率结果也较为理想。经合作实验室、美国FDA和美国戴安公司多方验证,该方法可作为标准方法进行推广。A simple ion chromatography method was described for the direct determination of benzoate in liquid food products. Brand -new ICS- 3000 ion chromatography system with reagent free eluent generation device were used with high capacity IonPac AS18 column by which standard solutions and actual samples were analysed and the results are satisfied. Only dilution and de - gas process need to be done before injection. This method which has the advantages of easy operation, good reproducibility, high sensitivity etc and the spiked results are very good as well. Proven by our cooperation labs, US FDA and US Dionex, this method can be used as the standard method to analyse Benzoate in food and Beverage matrix.
