The end point of mixed bed operation in condensate polishing system is commonly cotrolled only by hydrogen conductivity index

its defect is unaccurate judgement of the end point.The ion chromatography can rapidly and accurately detect the ion content of trace impurities in highly pure water

hence

it is helpful to judge the end point of mixed bed operation.Furthermore

in the case of problem occurring in mixed bed operation and regeneration of the condensate polishing system

the ion chromatographic technology can also be used to analyse where the problem lies.Combined with practice in power plants

the application situation of ion chromatographic technology in condensate polishing systems has been presented in detail.
