稀有氣體、永久氣體以及低碳烴類氣體等的分析檢測,是近代工業(yè)和環(huán)境保護(hù)中的一個(gè)重要問題。隨著生產(chǎn)和科研事業(yè)的迅速發(fā)展,我國已經(jīng)開始廣泛地采用色譜技術(shù)來解決這類課題。用氣相色譜法分析上述氣體,一般采用分子篩、硅膠和活性碳等作為分離柱。但這些吸附劑往往由于分離能力或柱壽命的限制,不能滿意地應(yīng)用。后來發(fā)展的高分子多孔小球雖然對某些氣體有較好的分離能力,但對于復(fù)雜的多組分混合物仍需較繁雜的操作條件。近年來合成的碳分子篩對某些無機(jī)氣體和低碳烴類的分離顯示了良好的性能。這些新型固定相的發(fā)展使上述氣體的分離效果有了顯著的提高。

The analysis and detection of rare gases, permanent gases, and low-carbon hydrocarbon gases is an important issue in modern industry and environmental protection. With the rapid development of production and scientific research, China has begun to widely use chromatography technology to solve such problems. Gas chromatography is used to analyze the above gases, usually using molecular sieves, silica gel, and activated carbon as separation columns. However, these adsorbents often cannot be satisfactorily applied due to limitations in separation capacity or column life. Although the later developed polymer porous microspheres have good separation ability for certain gases, they still require complex operating conditions for complex multi-component mixtures. In recent years, synthesized carbon molecular sieves have shown good performance in separating certain inorganic gases and low-carbon hydrocarbons. The development of these new fixed phases has significantly improved the separation efficiency of the aforementioned gases.
