【摘要】 本文叙述了制作微型电导池的一种方法。用微型电导池、直流高压发生器、电导仪、记录仪等组装了一套高效毛细管电泳－电导检测装置。HPCE－CD装置已被用于天然矿泉水中碱金属离子及人发中氨基酸的测定。获得的结果是令人满意的。在最佳实验条件下，对Li-Na-、K-的检测限分别为5．0×108mol／L。更多还原

【Abstract】 A method for making micro conductivity cell was described. An instrument ofHPCE and CD was assembled with a micro conductivity cell, direct current high voltage generator. conductometer, recorder etc. and used for the determination of alkali metal ions innatural mineral water and amino acids in human hair. Results obtained were satisfactory.The limit of detection is 5. 0 ×10 8mol/L for ions Li’, Na+ and K+ in optimum experimentalconditions .更多还原
