摘要
文章分析了紫外差分吸收光谱技术的NOx紫外平台,该平台用直接方式测量NO、NO2气体浓度,相对误差在2%以内,且示值误差小于15ppm;平台响应时间T95小于4.5s;重复性指标中NO和NO2的相对标准偏差分别为0.105%和0.116%。平台能够精准测量汽车尾气中的NO、NO2浓度。
This paper analyzed a NOx ultraviolet platform based on the UV-DOAS technology.The platform directly measures the concentration of NO and NO2 gases,with a relative error of less than 2%,and an indication error of less than 15ppm.The response time(T95)of the platform is less than 4.5s.The relative standard deviation of NO and NO2 in terms of repeatability was 0.105%and 0.116%.The platform can accurately measure the concentration of NO and NO2 in automobile exhaust.
