摘　　要：以在线总有机碳分析仪为例,探讨了某碱业有限公司总有机碳分析仪COD_(Cr)-TOC的转换系数。通过仪器性能的调试测试,仪器的24H飘移、量程飘移、重复性实验均满足(HJ/T353-2019)中关于TOC在线仪器相应的性能要求,仪器运行稳定、可靠、准确。利用了生产废水的TOC标准样品的加标试验,一共进行了三个氯离子浓度级别下9组共18个加标样品。它们的加标回收率在92.3%~102%之间,符合要求。In the case of the online total organic carbon analyzer,the conversion coefficient of TCO was discussed.Through the debugging test of the instrument performance,the 24H drift,range drift and repeatability experiments of the instrument all met the corresponding performance requirements of TOC online instrument in(HJ/T 353-2019),and the instrument operation was stable,reliable and accurate.Using the labeling test of TOC standard samples of production wastewater,9 groups of 18 spiked samples under three chloride ion concentration levels were conducted.Their spike recovery rate was between 92.3%and 102%,which met the requirements.
