摘　　要：为满足环境空气异味污染溯源和连续监测的需要,研制了一种基于气相色谱及光学检测技术的异味污染物在线监测系统,从硬件与软件两方面描述了该监测系统的功能特点,并进一步对氮磷检测器响应校正系统和采样歧管进行了开发。实验室标气测试结果显示该系统检出限小于0.1 nmol/mol,重复性相对标准偏差小于2.0%,线性相关系数大于0.99。该系统已应用于卷烟厂等工业园区的移动监测污染溯源和站点连续监测,取得了满意的效果。异味污染物在线监测系统具有良好的准确性、稳定性和应用性,能够满足环境空气异味污染监控的需求。In order to meet the needs of tracing and continuous monitoring of odor pollution in ambient air,an online odor pollutants monitoring system based on gas chromatography and spectral detection was developed.The functions and characteristics of the system were described in detail from both hardware and software.The response correction system of nitrogen phosphorus detector and sampling manifold were further developed.The test results show that the detection limit of the system is less than 0.1 nmol/mol,with the relative standard deviation of repeatability less than 2%,and the correlation coefficient of the calibration curve is more than 0.99(more than 0.999 for hydrogen sulfide and ammonia).The application cases of the system for mobile monitoring pollution tracing and site continuous monitoring are also introduced.The results show that the online monitoring system of odor pollutants has good accuracy,stability and field application ability,and can meet the requirements of odor pollution monitoring.
