气体中甲烷、氧化亚氮和二氧化碳浓度测定 气相色谱法
10月26日，日内瓦/纽约（WMO）— 根据世界气象组织（WMO）一份新报告，在另一个充满不祥之气的气候变化警报中，三种主要温室气体：二氧化碳、甲烷和氧化亚氮的大气水平在2021年均创下了新高。

2021年的二氧化碳浓度为百万分之415.7（ppm），甲烷为十亿分之1908（ppb），氧化亚氮为334.5ppb。这些数值分别占工业化前（人类活动开始破坏大气中这些气体的自然平衡之前）水平的149%、262%和124%。

浩瀚色谱研制生产的HH-N2O-Ⅳ填充柱，一次进样即可实现甲烷，二氧化碳和氧化亚氮的分离，柱效高，分离较好，面积外标法定量。

Determination of methane, nitrous oxide, and carbon dioxide concentrations in gases - Gas chromatography method

On October 26th, Geneva/New York (WMO) - According to a new report from the World Meteorological Organization (WMO), in another ominous climate change alert, atmospheric levels of three major greenhouse gases: carbon dioxide, methane, and nitrous oxide reached new highs in 2021.



The carbon dioxide concentration in 2021 is 415.7 parts per million (ppm), methane is 1908 parts per billion (ppb), and nitrous oxide is 334.5 ppb. These values account for 149%, 262%, and 124% of pre industrial levels (before human activities began to disrupt the natural balance of these gases in the atmosphere), respectively.



The HH-N2O - IV packed column developed and produced by Haohan Chromatography can achieve the separation of methane, carbon dioxide, and nitrous oxide in one injection, with high column efficiency and good separation. The area external standard method is used for quantification.
