基于紫外光度法新型臭氧自动监测仪Model 205的性能研究

臭氧作为光化学污染气体逐渐被人们所关注,也成为我国大气环境保护领域关注的重点问题,因此对臭氧进行自动监测就成为了我国环境保护与科学研究的必要手段。为了了解2B Technologies公司生产的Model 205新型便携式臭氧自动监测仪的使用方法与精度性能特点,利用符合标准实验室要求的美国Thermo Fisher Scientific公司生产的Model 49i型臭氧自动监测仪器作为对比,使用Model 49ips臭氧校准仪对两台仪器分别进行校准,并于2016年7月28~29日进行了22 h的近地面臭氧浓度的实时监测。通过与Model 49i的监测结果进行线性相关分析,发现Model 205的测量结果精度较高,在实际监测工作中具有很好的适用性。

Abstract

The surface ozone,as one of the photochemical pollutions,has attracted public attention in the field of atmospheric environmental protection.Thus,it is necessary to monitor the ozone with automatic instruments.In this paper,a new type of portable ozone automatic monitor(Model 205),which is made by 2B Technologies Co.,is examined to estimate its usage and precision.During the experiment,the Model 49i produced by the Thermo Fisher Scientific company was used as a comparison with the Model 205,and a surface ozone calibrator(Model 49i-ps) is used to generate the standard for Model 205 and Model 49i,respectively.During July 28,2016 to July 29,natural air was continuously monitored by the two instruments at the same time.We found that the accuracy of the Model 205 was similar with Model 49i,so it can be concluded that Model 205 has a good applicability in the practical work.
