摘要抑制系统是抑制型(双柱型)离子色谱系统极为重要的一个组成部分,也是离子色谱有别于其它类型的液相色谱的最重要特点之一。抑制器的发展经历了多个发展时期,而目前商品化的离子色谱仪亦分别采用不同形式的抑制手段。近年来,还发展了一些特殊的辅助抑制器,如接在抑制器后面CO2除去装置,用于提高被测离子的信号或进一步降低背景电导值。 Suppression system is a very important part of suppressed ion chromatograph with double columns,and is also the typical characteristic of ion chromatograph,which differs from other types of liquid phase chromatograph.It has experienced several development stages of suppressor,and different forms of suppression system have been used in commercial ion chromatograph currently.In recent years,some special assisted suppressors such as CO2 removal device installing on the back of suppressor,have been adopted to improve the measured signals and decrease background conductivity values.
