聯(lián)合國氣候變化框架公約下總共有六種非二氧化碳溫室氣體,可分為三大類:甲烷、氧化亞氮、含氟氣體(包括氫氟碳化合物(HFCs)、全氟化碳(PFCs)、六氟化硫(SF6)和三氟化氮(NF3))。其中,CH4和N20是自然界中本來就存在的成分,由于人類活動而增加,而含氟氣體HFCs、PFCs、SF6和NF3則完全是人類活動的產(chǎn)物。非CO2溫室氣體(除甲烷外)的排放多與能源消費有直接關(guān)系,與工業(yè)化、城市化和農(nóng)業(yè)現(xiàn)代化呈正相關(guān),在全球增溫中的作用不可忽略。
長期以來的中國應(yīng)對氣候變化政策的重心主要集中在CO2溫室氣體排放,而忽略了非CO2溫室氣體排放。但實際上,中國面臨的非CO2溫室氣體排放壓力正日益嚴(yán)峻,其控制必須納入應(yīng)對氣候變化的總體戰(zhàn)略之中。

There are a total of six non carbon dioxide greenhouse gases under the United Nations Framework Convention on Climate Change, which can be divided into three categories: methane, nitrous oxide, and fluorinated gases (including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride (SF6), and nitrogen trifluoride (NF3)). Among them, CH4 and N20 are components that already exist in nature and have increased due to human activities, while fluorinated gases such as HFCs, PFCs, SF6, and NF3 are entirely products of human activities. The emissions of non-CO2 greenhouse gases (excluding methane) are directly related to energy consumption and positively correlated with industrialization, urbanization, and agricultural modernization. Their role in global warming cannot be ignored.
For a long time, the focus of China's climate change policies has mainly been on CO2 greenhouse gas emissions, while neglecting non-CO2 greenhouse gas emissions. However, in reality, China is facing increasingly severe pressure on non-CO2 greenhouse gas emissions, and its control must be included in the overall strategy to address climate change.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. adopts a capillary chromatography column for the determination of greenhouse gases CH4, N2O, and CO2 using programmed temperature gas chromatography
One injection analysis of oxidized nitrogen and carbon dioxide in the atmosphere
Compared with methane, it has high column efficiency, good separation, and symmetrical peak shape. It has achieved good results on Agilent, Shimadzu, Thermo Fisher, Varian, Brooke, and PE.
