本文研究离子色谱电化学抑制器的填料问题，提出以直径大小一致、中等磺化深度的球状树脂为最佳方案．改进后的抑制效率达９９．９８％，灵敏度提高了约１０％，离子的峰高及保留时间的重现性均优良（ｃ．ｖ．＜２）．
The packings of electrochemical suppressor on ion chromatography were studied,It was found that the best packing is the appropriately sulfonate globular resins uniform in size.Using these resins,suppression efficiency was improved to 99.98%,and sensitivity improves about 10%,the reproducibilities of both the height of ion peaks and retention time are very good(c.v<2).
