自1975年H·Small等提出离子色谱法(简称IC)以来,近十年中有了很大的发展。到目前为止,该方法除了能测定几十种无机阴离子和阳离子外,还能测定有机酸、糖类、醇类、氨基酸和肽类等有机化合物。离子色谱仪由交换容量很低的阴(或阳)离子交换柱(分离柱)、交换容量高的阳(或阴)离子交换柱(抑制柱)和电导检测器等器件组成。在分析阴离子时,常用的 Since 1975, H · Small et al proposed ion chromatography (referred to as IC), the last decade has been great development. So far, this method can not only measure dozens of inorganic anions and cations, but also determine organic compounds such as organic acids, sugars, alcohols, amino acids and peptides. Ion chromatography by the exchange capacity is very low anion (or cation) ion exchange column (separation column), exchange capacity Yang (or anion) ion exchange column (inhibition column) and conductance detector and other components. In the analysis of anions, commonly used
