A novel concept of simultaneous injection-effective mixing analysis (SIEMA) is proposed, and a SIEMA method applied to the spectrophotometric determination of palladium using a water-soluble chromogenic reagent has been demonstrated. The flow configuration of SIEMA is a hybrid format of flow injection analysis (FIA), sequential injection analysis (SIA) and multicommutation in flow-based analysis. Sample and reagent solutions are aspirated into each holding coil through each solenoid valve by a syringe pump, and then the zones are simultaneously dispensed (injected) into a mixing coil by reversed flow toward a detector through a confluence point. This results in effective mixing and rapid detection with low reagent consumption.
提出了一种同时进样-有效混合分析（SIEMA）的新概念，并展示了一种将SIEMA方法应用于使用水溶性显色剂分光光度法测定钯的方法。SIEMA的流动配置是流动注射分析（FIA）、顺序注射分析（SIA）和流动分析中的多换向的混合形式。样品和试剂溶液通过注射泵通过每个电磁阀吸入每个保持线圈，然后通过汇合点以逆流方式将这些区域同时分配（注入）到混合线圈中，朝向检测器。这导致有效混合并以低试剂消耗进行快速检测。
