甲烷（CH4）、二氧化碳（CO2）和氧化亞氮（N2O）等具有溫室效應(yīng)的微量氣體稱為溫室氣體。
根據(jù)京都議定書(shū)中規(guī)定的6種溫室氣體為二氧化碳、甲烷、氧化亞氮、氫氟碳化合物、全氟碳化合物、六氟化硫。
后三種氣體造成溫室效應(yīng)的能力最強(qiáng)，但從對(duì)全球升溫的貢獻(xiàn)來(lái)說(shuō)，CO2、CH4、N2O三大主要溫室氣體所占的比例最大，對(duì)全球變暖的總體貢獻(xiàn)占到77%，濃度也呈現(xiàn)出逐年升高的趨勢(shì)。
大氣中CO2、CH4和N2O三種組分是目前溫室氣體監(jiān)測(cè)的主要對(duì)象，也是當(dāng)前世界各國(guó)控制減排的主要溫室氣體組分。

Trace gases such as methane (CH4), carbon dioxide (CO2), and nitrous oxide (N2O) that have a greenhouse effect are called greenhouse gases.
According to the Kyoto Protocol, the six greenhouse gases are carbon dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons, and sulfur hexafluoride.
The latter three gases have the strongest ability to cause greenhouse effect, but in terms of their contribution to global warming, CO2, CH4, and N2O are the three main greenhouse gases with the largest proportion, accounting for 77% of the overall contribution to global warming, and their concentrations are also showing an increasing trend year by year.
The three components of CO2, CH4, and N2O in the atmosphere are currently the main objects of greenhouse gas monitoring, and they are also the main greenhouse gas components controlled and reduced by countries around the world.
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a capillary chromatography column for the determination of carbon dioxide, methane, and N2O. The column uses a single capillary column to directly measure the fluxes of CO2, CH4, and N2O in the atmosphere at a constant temperature. The analysis time is short, the column efficiency is high, and the separation is good.
Name: Capillary Column
Specification: 50m * 0.53mm
Model: HH-CO2-CH4-N2O
Application: Direct injection determination of carbon dioxide, methane, and oxidized nitrogen in the atmosphere using a capillary column
characteristic:
