浩瀚色谱（山东）应用技术开发有限公司以碳分子筛作为吸附剂时,多孔层毛细管柱的制备方法,并用它在不同条件下对永久性气体以及C_1～C_6烃类气体进行了分离及分析。这类色谱柱可以使C_6烃在350℃馏出,不同碳数的烃类严格按碳数分开,不存在不同碳数间交叉的现象。在4℃时还可使O_2、N_2、CO很好分离,但对C_4异构体的分离不理想.如以k′值来代替涂层厚度(df)作为柱参数时,对HEPT～k′的曲线分析显示:减小颗粒直径、增加涂层厚度,有助于提高涂层均匀性和多孔层色谱柱的柱效。

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. used carbon molecular sieve as adsorbent, the preparation method of porous layer capillary column, and used it to separate and analyze permanent gas and C_1-C_6 hydrocarbon gas under different conditions. This type of chromatographic column can distill C_6 hydrocarbons at 350℃. Hydrocarbons with different carbon numbers are strictly separated by carbon number, and there is no crossover phenomenon between different carbon numbers. At 4℃, O_2, N_2, and CO can also be well separated, but the separation of C_4 isomers is not ideal. For example, when the k' value is used instead of the coating thickness (df) as the column parameter, for HEPT~k' The curve analysis shows that reducing the particle diameter and increasing the thickness of the coating can help to improve the uniformity of the coating and the column efficiency of the porous layer column.
