The metal organic framework material UiO-66 was used as an adsorbent,coated on a capillary column,aged un-der high-purity nitrogen gas,and connected to gas chromatography for the hydrocarbons analysis of C4 and below.Firstly,UiO-66 was synthesized,and then UiO-66 was prepared into suspension and coated on the inner wall of capillary column by static coating method.After multiple coatings and reaching the desired thickness,according to the set gas chromatography analysis conditions,more than 14 types of low-level hydrocarbons can be separated.The separation degree far exceeds 1.2,and the column efficiency is calculated to reach 2500/m using ethane.The tailing factor is within 1.2,which can be fully applicable to actual industrial production.
