本标准适用于公共场气空气中二氧化碳浓度的测定。

CO2在正常大气中含量为0.03%,当浓度达到0.05%时就会对人体产生危害.CO2的增加还将影响气温变化,促进大气污染的发生,危害人类的生存环境.另外CO2在所有温室效应气体中,对温室效应的作用较大,占60%.因此,CO2已成为温室气体削减与控制的重点.但目前我国还没有制订出CO2的标准分析方法,推荐的分析方法有非分散红外气体分析仪法、容量滴定法和气相色谱法.现多采用非分散红外线气体分析仪法,此方法的缺点是无法消除CO、碳氢化合物和水气的干扰.

为此,浩瀚色谱（山东）应用技术开发有限公司建立了能消除CO、碳氢化合物和水气干扰的准确、灵敏、精密、快速检测分析方法-气相色谱法，外标定量，结果满意。

Determination of the concentration of carbon dioxide in the atmosphere and indoor air Details:

Name: Packed column
Material: Stainless steel
Stationary phase: high molecular porous polymer
Specification: 3m*4mm (inner diameter)
Model: GDX-102
Granularity: 60-80 mesh
Application: GGB/T 18204.24-2000 Determination of carbon dioxide in the air of public places

This standard specifies the method for determining the concentration of carbon dioxide in the air in public places.
This standard applies to the determination of the concentration of carbon dioxide in the air in public places.

The content of CO2 in the normal atmosphere is 0.03%, and when the concentration reaches 0.05%, it will cause harm to the human body. The increase of CO2 will also affect temperature changes, promote the occurrence of air pollution, and endanger the living environment of human beings. In addition, CO2 is in all greenhouse effects. Among the gases, the greenhouse effect is greater, accounting for 60%. Therefore, CO2 has become the focus of greenhouse gas reduction and control. However, China has not yet formulated a standard analysis method for CO2, and the recommended analysis method is non-dispersive infrared gas Analyzer method, volumetric titration method and gas chromatography method. Nowadays, non-dispersive infrared gas analyzer method is mostly used. The disadvantage of this method is that it cannot eliminate the interference of CO, hydrocarbons and moisture.

To this end, Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. established an accurate, sensitive, precise, and rapid detection and analysis method that can eliminate the interference of CO, hydrocarbons and water vapor-gas chromatography, with external standard quantification, and the results are satisfactory.
