浩瀚色谱（山东）应用技术开发有限公司对典型企业固定污染源非甲烷总烃在线监测系统开展比对监测,通过对比分析自动监测系统与手工方法监测数据的相关性;通过性能指标测试、方法比对等获取系统的性能指标、检测结果等方面的基础数据。测试结果表明实际样品比对过程中采用不同的采样分析仪器,监测结果差距较大,相对误差在1.23%～108.1%,便携式分析仪结果相对误差较小,实验室分析结果相对误差较大。系统线性误差与量程漂移可以满足现阶段管理要求,并根据测试结果为在线监测系统运行管理提出建议。

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. carried out comparative monitoring of the non-methane total hydrocarbon online monitoring system of fixed pollution sources of typical enterprises, and analyzed the correlation between automatic monitoring system and manual method monitoring data; passed performance index testing and method comparison Obtain basic data such as system performance indicators and test results. The test results show that different sampling and analysis instruments are used in the actual sample comparison process, and the monitoring results have a large gap, with a relative error of 1.23% to 108.1%. The portable analyzer results have relatively small relative errors, and the laboratory analysis results have relatively large relative errors. The linear error and range drift of the system can meet the management requirements at this stage, and suggestions for the operation and management of the online monitoring system are put forward based on the test results.
