双柱离子色语法亦称抑制型离子色谱,由于该法检测系统采用通用电导检测器,当洗脱液从分离柱洗脱待测离子时,洗脱液本身有大的背景电导,必须置一个与分离离子电荷相反的离子交换树脂柱或装置于分离柱 Double-column ion chromatography, also known as suppressed ion chromatography, the detection system using universal conductivity detector, when the eluent eluted from the separation column to be measured when the eluent itself has a large background conductance, you must set a An ion exchange resin column or device that separates ionic charge from the separation column
