摘　　要：花园口水质自动监测站引进了全自动在线监控系统CMS5000，集采样、样品分析、数据处理自动化于一体。通过试验研究，建立了同时在线快速有效地监测水中24种挥发性有机物的方法，线性相关系数为0．993以上，检出限为0．08—0．60μg/L、相对标准偏差为0．6％～3．5％、回收率为79％～122％。通过与实验室常规气相色谱法比测，证明CMS5000系统是稳定可靠的，可用于日常和突发性水污染事故中挥发性有机物的监测。Huayuankou Automatic Water Quality Monitoring Station has imported CMS5000 automatic online monitoring system, integrating sam- pling, sample analysis and data processing automation into a whole. Through the experimental study, a method of online simuhaneous fast and ef- fective monitoring 24 kinds of volatile organic compounds in water was established, with the correlation coefficients over 0. 993, the determination limits of 0.08 - 0.60μg/L, the relative standard deviation of 0.6% -3.5% and the recovery rates of 79% - 122%. Compared with the conven- tional gas chromatography in the laboratory, the result shows that the CMSS000 system is stable and reliable. It can be used for monitoring of vola- tile organic compounds in water daily and sudden pollution accidents.
