Air transported samples of a mixture containing the analyte and a supporting electrolyte are consecutively propelled into a microconduit system through a titration cell, a coil and a detector cell. Different amounts of electrochemically generated titrant are obtained in the separate samples while they are passing through the titration cell. Various quantities of the titrant are achieved by changing the duration of the titrant generating process that is done by various time for the sample solution staying in the titration cell (different sample movement rate). The titrated sample is then homogenised in the coil and detected in an electrochemical detector cell that supplies necessary data for the analyte determination. The declared method is experimentally verified on coulometric titration of hydrochloric acid (HCl) with electrogenerated sodium hydroxide and a titration of aniline with bromine generated in a bromide solution.
通过滴定池、线圈和检测池，将含有分析物和支持电解质的混合物的空气传输样品连续推进微导管系统。当单独的样品通过滴定池时，在其中获得不同量的电化学产生的滴定剂。通过改变滴定剂产生过程的持续时间来实现不同量的滴定剂，该过程通过样品溶液在滴定池中停留的不同时间（不同的样品移动速率）来完成。然后将滴定后的样品在线圈中均匀化，并在电化学检测池中进行检测，该检测池为分析物的测定提供必要的数据。所宣称的方法已通过用电化学产生的氢氧化钠对盐酸（HCl）进行库仑滴定以及用溴化物溶液中产生的溴对苯胺进行滴定的实验验证。
