GDX-502甲烷柱气相色谱法检测废气中甲烷,非甲烷总烃
GDX-502甲烷柱气相色谱法检测废气中甲烷,非甲烷总烃 详细信息：
随着经济社会的发展,不断扩大的工业生产向空气中排放着大量污染物,这就需要准确的检测数据以实现有效的环境管理.气相色谱法检测废气中的甲烷,非甲烷总烃,应用甲烷作为标准参考气体较为合适,与丙烷比较,对非甲烷总烃的定量没有较大差别,且时间上明显缩短,提升了作业效率;在仪器配置上,建议采用双柱配置的气相色谱,一次进样做完所有分析,效率更高,而且能够有效提高实验结果的准确性;手工配制方法尽管有些麻烦,但也能较好的满足实验要求,且成本更低;与毛细管柱相比来说,填充柱的检出限尽管稍差,但成本更低,已经能够满足实验要求;在样品采集环节,污染源具有负压时,需要选用动力采样,而其余情况以及无组织排放,采用玻璃注射器采集,再注入惰性气袋存放即可,这样不但提高了采集效率,而且更加方便运送,气密性也很好。

Determination of methane and non-methane total hydrocarbons in waste gas by GDX-502 methane column gas chromatography
GDX-502 Methane Column Gas Chromatography Detection of Methane and Non-Methane Total Hydrocarbons in Exhaust Gas Details:
With the development of economy and society, the expanding industrial production emits a large amount of pollutants into the air, which requires accurate detection data to achieve effective environmental management. Gas chromatography is used to detect methane and non-methane total hydrocarbons in exhaust gas. Methane is more suitable as a standard reference gas. Compared with propane, there is no significant difference in the quantification of non-methane total hydrocarbons, and the time is significantly shortened, which improves the operation efficiency. It is more efficient and can effectively improve the accuracy of the experimental results after all the analysis is done after the injection , the detection limit of the packed column is slightly worse, but the cost is lower, and it can meet the experimental requirements; in the sample collection process, when the pollution source has negative pressure, it is necessary to use dynamic sampling, and in other cases and fugitive emissions, use glass syringes to collect , and then inject into the inert gas bag for storage, which not only improves the collection efficiency, but also facilitates transportation and has good air tightness.
