专利汇可以提供Alkaline metal ion detection专利检索,专利查询,专利分析的服务。并且PURPOSE:To detect alkaline metal ions selectively regardless of the influence of heat by a method wherein the alkaline metal ion components are separated one after another from a specimen containing the alkaline metal ions by an ion exchange resin and detected by cyclic voltammetry. CONSTITUTION:In the case of selective quantitative analysis of Na , a specimen is introduced from a moving phase solution sink 1 into an ion exchange column 4 through by a solution feeding pump 2. A flow path from the column 4 is switched to a waste solution sink 7 by a switching valve 6. When a retention time of Na comes near, the valve 6 is switched to feed the eluate into a cell 8 and after Na is sufficiently separated, the valve 6 is switched to the waste solution sink 7. The solution in the cell 8 is scanned by a voltage and a cyclic voltamgramm is recorded. When K and Rb are to be detected, the same measurement is performed by switching the valve 6 corresponding to the retention time. With this constitution, alkaline metal ions are selectively detected regardless of the influence of heat.,下面是Alkaline metal ion detection专利的具体信息内容。
