在离子色谱中固定相与流动相之间发生离子的可逆交换,利用溶质离子对固定相亲和力的差别来完成离子色谱分离,离子色谱中的固定相就是离子交换树脂。目前应用最广的交换树脂是含有网状的交联结构聚合物 In ion chromatography reversible ion exchange occurs between the stationary phase and the mobile phase, ion chromatography separation is performed using the difference in affinity between the solute ions and the stationary phase, and the stationary phase in the ion chromatography is the ion exchange resin. Currently the most widely used exchange resin is a network of cross-linked polymers
