Abstract
The invention discloses a high concentration chloride ion analysis system, which includes a sampling system. The sampling system consists of a buffer pool and a measurement pool that are respectively connected to a system header pipe and an analysis control system. The buffer pool is in connection with the system header pipe through a master valve, and the pipeline connecting the buffer pool and the measurement pool is provided with a metering pump. The measurement pool is connected to a dilution flushing pump and a dosing pump, the dilution flushing pump pumps non-chlorine water in a non-chlorine water tank into the measurement pool to dilute the sample, and the dosing pump pumps the medicinal liquid in a reagent tank into the measurement pool to carry out analytical reaction treatment. After precise sampling and accurate multiple dilution on the high concentration chloride ions in complex media, the system provided by the invention conducts content determination, thus solving the problem that existing chloride ion electrode content determination methods cannot detect gram-scale high concentration chloride ions.
