通过对7种废气自动监测系统的比较研究和现场测试，提出了非分散红外法、紫外差分法、紫外荧光法、化学发光法等多种 SO2和 NO x 自动监测技术在低浓度范围实现准确定量监测的性能评价方法，定义了 CEMS 的系统检出限及其主要影响因素。建议采用系统检出限、线性误差等关键参数作为低浓度 CEMS 的性能评价方法，提出将全系统多点标准气体校准或加标回收率作为验收和质控监督的基本方法。

Based on the comparative studies and field testing on seven kinds of CEMS,the performance e-valuation methods of NDIR,UV-Difference,UV Fluorescence and Chemiluminescent were put forward for the ac-curate quantification of SO2 and NO x at low concentrations in flue gases form stationary sources.The system detec-tion limit of CEMS was defined and its main influencing factors were discussed.The system detection limit and linearity error were recommended to be key parameters of performance evaluation.Multi-point calibration or spiked recovery was suggested to be the base method of acceptance check and quality control.
