摘要
为了提升水质自动监测能力,对CMS5000仪器在线测定地表水中挥发性有机物进行了研究。研究表明,该仪器的线性好、检测限低、精密度和精确度高;和实验室方法相比,其总体误差较小;采水管路对特定组分的测量有一定影响。因此该方法能适应水质自动监测的需要,但是对其采样系统提出了更高的要求。
In order to improve the ability to automatically monitor the surface water,the CMS5000 on line analyzer was studied to monitor the VOCs in surface water.The results indicated that this analyzer had good linearity,low detection limit,high precise and accuracy.Contrast to the laboratory method,the total error was small.The sample pipeline effect the monitor results in some special elements.So this method met the requirement of water automatic monitoring system,but need to upgrade the sample system.
