氮氧化物气体浓度监测的研究

Study on Nitrogen Oxide Gas Concentration Monitoring

为了研究氮氧化物(NOx)监测的分析方法以及可能出现的问题,本文以氮氧化物分析仪检测氮氧化物为实验对象,分别对是否校准、定值标准的选择和不同工作模式下氮氧化物浓度的测评结果进行探究。由此得出,氮氧化物分析仪的工作机制是按照自动模式工作的,没有进行校准所得出的数据不具有科学性,会得出错误的分析结果,选择浓度适当的标准物质对提高分析结果的准确度有重要的意义。

In order to study the analytical methods and possible problems of nitrogen oxide(NOx)monitoring.This paper uses NOx analyzer to detect NOx as the experimental object,the evaluation results of NOx concentration ae investigated.It is concluded that the working mechanism of the nitrogen oxide analyzer is that the data obtained without calibration is not scientific when it is operated according to the automatic mode,so it is of great significance to obtain the wrong analysis result and the selection of the standard material with the appropriate concentration to improve the accuracy of the analysis result.
