在城市燃气中氨含量的分析方法上,现在执行的是GB12210-90标准.其中取样时燃气流速规定在0.25～0.5L/min,并要求吸收的氨量控制在 2～30mg范围内.当燃气中的氨含量在50mg/m3(出厂煤气月平均含氨量在24.3～177.3mg/m3),平均取样 速度为0.38L/min,平均吸收的氨量为16mg,则需取0.32m3煤气.取样时间为320/0.38=842min,合14个多小时.由此可见, 取样需要的时间很长,而当煤气中氨含量较低时(经常有<20mg/m3),则需要采样时间更长。

The analysis method for ammonia content in urban gas is currently based on the GB12210-90 standard The gas flow rate during sampling is specified as 0.25-0.5L/min, and the amount of ammonia absorbed is required to be controlled within the range of 2-30mg When the ammonia content in the gas is 50mg/m3 (the average monthly ammonia content in the factory gas is 24.3-177.3mg/m3), the average sampling rate is 0.38L/min, and the average absorbed ammonia is 16mg, 0.32m3 of gas needs to be taken The sampling time is 320/0.38=842 minutes, which is over 14 hours From this, it can be seen that the sampling time is very long, and when the ammonia content in the gas is low (often<20mg/m3), a longer sampling time is required.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has successfully developed the gas chromatography method for the determination of ammonia in coal gas using Shimadzu packed chromatography column
The key lies in "system inertness" and "effective separation".
Targeted optimization and validation of sampling, chromatographic columns, and operating conditions are required based on specific gas composition, ammonia concentration range, and laboratory conditions.
High column efficiency and good separation
