二氧化碳灭火剂是以液态的形式加压充装在灭火器中，由于二氧化碳的平衡蒸汽压高，瓶阀一打开，液体立即通过虹吸管、导管和喷嘴并经过喷筒喷出，液态的二氧化碳迅速汽化，并从周围空气中吸收大量的热，（1千克液态二氧化碳气化时需要578KJ热量）但由于喷筒隔绝了对外界的热传导，因此二氧化碳液态气化时，只能吸收自身的热量。导致液体本身温度急剧降低，当其温度下降到零下78.5摄氏度（升华点）时，就有细小的雪花状二氧化碳固体出现。所以以灭火剂喷射出来的是温度很低的气体和固体的二氧化碳，尽管二氧化碳温度很低，对燃烧物有一定的冷却作用，然而这种作用远不足以扑灭火焰。

它的灭火作用主要是增加空气中不燃烧、不助燃的成分，使空气中的氧气含量减少，实验表明：燃烧区域空气中氧气的浓度小于等于百分之十二，二氧化碳的浓度为百分之三十到百分之三十五时，绝大多数的燃烧都会熄灭。

二氧化碳具有较高的密度，约为空气的1.5倍。在常压下，液态的二氧化碳会立即汽化，一般1kg的液态二氧化碳可产生约0.5立方米的气体。灭火时，二氧化碳气体可以排除空气而包围在燃烧物体的表面或分布于较密闭的空间中，降低可燃物周围或防护空间内的氧浓度，产生窒息作用而灭火。另外，二氧化碳从储存容器中喷出时，会由液体迅速汽化成气体，而从周围吸引部分热量，起到冷却的作用。

浩瀚色谱（山东）应用技术开发有限公司，，采用毛细管柱测定二氧化碳灭火剂，面积归一法定量，结果准确。

Carbon dioxide fire extinguishing agent GB 4396-2005
Carbon dioxide fire extinguishing agent GB 4396-2005 detailed information:

Name: Capillary Column
Specification: 15m*0.53mm*50um
Model: HH-PLOT molecular sieve 5A

The carbon dioxide fire extinguishing agent is pressurized and filled in the fire extinguisher in liquid form. Due to the high equilibrium vapor pressure of carbon dioxide, as soon as the bottle valve is opened, the liquid immediately passes through the siphon, pipe and nozzle and sprays out through the nozzle, and the liquid carbon dioxide is quickly vaporized. It absorbs a lot of heat from the surrounding air, (578KJ of heat is required for the gasification of 1 kg of liquid carbon dioxide). However, because the spray tube isolates the heat conduction to the outside, when the carbon dioxide is gasified, it can only absorb its own heat. As a result, the temperature of the liquid itself drops sharply. When its temperature drops to minus 78.5 degrees Celsius (sublimation point), fine snowflake-like carbon dioxide solids appear. Therefore, the low-temperature gas and solid carbon dioxide sprayed out by the fire extinguishing agent, although the temperature of carbon dioxide is very low, has a certain cooling effect on the burning material, but this effect is far from enough to extinguish the flame.
Its fire extinguishing effect is mainly to increase the non-combustible and non-combustible components in the air, and reduce the oxygen content in the air. Experiments show that the concentration of oxygen in the air in the combustion zone is less than or equal to 12%, and the concentration of carbon dioxide is% At 30 to 35 percent, most of the combustion will go out.
Carbon dioxide has a higher density, about 1.5 times that of air. Under normal pressure, liquid carbon dioxide will vaporize immediately. Generally, 1kg of liquid carbon dioxide can produce about 0.5 cubic meters of gas. When extinguishing a fire, carbon dioxide gas can exclude air and surround the surface of the burning object or distribute it in a more confined space, reducing the oxygen concentration around the combustible or in the protective space, resulting in asphyxiating effect and extinguishing the fire. In addition, when carbon dioxide is ejected from the storage container, it will quickly vaporize from the liquid into a gas, attracting part of the heat from the surroundings, and play a cooling role.

Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. keeps pace with the times and uses capillary columns to determine carbon dioxide fire extinguishing agents. The area normalization method is used for quantification, and the results are accurate and reliable.
