甲烷（CH4）、二氧化碳（CO2）和氧化亚氮（N2O）等具有温室效应的微量气体称为温室气体。
根据京都议定书中规定的6种温室气体为二氧化碳、甲烷、氧化亚氮、氢氟碳化合物、全氟碳化合物、六氟化硫。
后三种气体造成温室效应的能力最强，但从对全球升温的贡献来说，CO2、CH4、N2O三大主要温室气体所占的比例最大，对全球变暖的总体贡献占到77%，浓度也呈现出逐年升高的趋势。
大气中CO2、CH4和N2O三种组分是目前温室气体监测的主要对象，也是当前世界各国控制减排的主要温室气体组分。

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:
1. Measurement with a capillary column
2. Constant temperature
One injection, directly measuring methane, carbon dioxide, and oxidized YA nitrogen
