浅析非甲烷总烃测定时采样气袋问题

Analysis of Problems About Sampling Gas Bag in Determination of Total Non-methane Hydrocarbons

非甲烷总烃是环境监测中相对常见和重要的一个指标。本文通过讨论和实验验证说明了非甲烷总烃监测中采样气袋在重复使用时空白的保证问题,如何实时地在不影响数据准确性的前提下有效的提高工作效率以及注意事项。

The content of total non-methane hydrocarbons is a relatively common and important indicator in environmental monitoring.In this paper,the guarantee problem of blank during the reuse of the sampling gas bag in non-methane total hydrocarbon monitoring is explained through discussion and experimental verification.And the paper also expounded how to effectively improve the work efficiency without affecting the accuracy of data in real time and some matters needing attention.
