利用国家环保部标准样品研究所已知标准气体,选取绵阳市的三个城市空气自动监测站进行二氧化硫实验分析。结果表明,EC9850B 二氧化硫监测仪跨漂后仪器响应快速升至最高值然后逐渐升高趋向稳定,通过连续跨漂的监测数据与已知标准气体的符合性确定仪器跨漂35min 后基本稳定,并在标准气体中值附近波动,据此开始记录数据,准确度高,数据有效且质量可控。

Using a standard gas from Institute for Environmental Reference Materials of Ministry of Environmental Protection,we an-alyzed the sulfur dioxide from three air automatic monitoring stations in Mianyang city.Experimental results showed that after span drift the signal response from the sulfur dioxide detection instrument EC9850B ramped quickly to a high value and then increased gradually before tending to stabilize.Comparing monitoring data from the known gas standard,it was established that the response spanned a drift time of 35 minutes before stabilization,and fluctuated near the standard median of the reference gas.Acquiring data starting from this point could improve the accuracy and efficacy of the data,and the quality could be under control.
