流动注射分析仪中氨氮模块的技术创新

Technological innovation of ammonia nitrogen module in fiow injection analyzer

流动注射分析仪中的氨氮模块与六价铬模块在检测器、六通阀、三通装置、蠕动泵、样品管线、试剂管线等方面有一定的共通性,经过科学的技术改造,可将氨氮模块用于六价铬的项目的测定,这样既可以优化六价铬的操作方法,用仪器法代替化学法。可以节省购买六价铬模块的费用又可以将氨氮模块物尽其用节约成本。

The fiow injection analyzer of ammonia nitrogen and hexavalent chromium module in detectors,six device,peristaltic pump valve,tee,sample line,reagent pipeline etc have certain convergence,through science and technology reform,ammonia nitrogen module can be used for the determination of hexavavalent chromium project,both to optimize the operation of hexavalent chromium method,by using the instrument method instead of chemical method.In addition,the waste liquid containing chrominm produced by chemical analysis of hexavalent chromium can be greatly reduced and the secondary pollution to the environment can be effectively rfduced.
