浩瀚色谱（山东）应用技术开发有限公司对某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,将在线监测结果和便携式仪器监测、手工监测结果作比对分析。结果表明,在线监测系统线性误差与量程漂移可以满足现阶段管理要求,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,便携式分析仪结果相对误差较小(为3. 72%),手工监测结果相对误差较大(为48. 3%)。建议加强污染源废气手工监测的质控管理,强化在线监测设备的运维管理,推进污染源非甲烷总烃CEMS合理有序发展。

online monitoring column system of non-methane total hydrocarbon from fixed pollution source

Details of online monitoring column system for non-methane total hydrocarbon of fixed pollution source:




Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. carried out comparative monitoring on the non-methane total hydrocarbon online monitoring system of a typical enterprise's fixed pollution source, and compared and analyzed the online monitoring results with the portable instrument monitoring and manual monitoring results. The results show that the linear error and range drift of the online monitoring system can meet the management requirements at this stage. Different sampling and analysis instruments are used in the actual sample comparison process, and the monitoring results differ greatly. The relative error of the portable analyzer results is small (3 72%), the relative error of manual monitoring results is relatively large (48 3%)。 It is suggested to strengthen the quality control management of manual monitoring of waste gas from pollution sources, strengthen the operation and maintenance management of online monitoring equipment, and promote the rational and orderly development of CEMS of non-methane total hydrocarbons from pollution sources.
