摘要：

差减凝胶渗透色谱(D-GPC)以已知的标准样品溶液作淋洗剂,样品溶液作进样试液,通过内部差减,快速准确地给出样品溶液与标准样品溶液各组分之间的差异。以聚乙二醇(PEG200)的浓度识别以及3种啤酒的品牌识别为例,通过比较常规GPC与D-GPC所得到的实验结果,说明D-GPC方法在啤酒质量控制和品牌识别等方面所具有的应用价值。

Abstract:

In differential gel permeation chromatographic method (D-GPC), a standard solution and an analyzed solution are used as the eluent and injected solution, respectively. It can determine the minute differences between them. When the analyzed solution and the standard solution are identical, a null signal is given, otherwise the nonzero signal tells the detailed differences between them. Two examples, the concentration identification of five polyethylene glycol 200 (PEG200) solutions and the brand identification of three brands of beers, are given to show the application of the D-GPC method. The potential applications of the D-GPC method in quality control and the identification of counterfeit products are also discussed.
