摘　　要：基于微机电技术制备了一种含有椭圆微柱阵列的半填充柱;采用水热法合成了一种金属有机骨架材料ZIF-8,将其涂敷在微色谱柱的微沟道内壁上作为固定相.在30℃恒温下对芯片的分离性能进行了测试,结果表明,以ZIF-8为固定相的微色谱柱可以在75 s内实现甲烷、乙烷和丙烷(C1~C3)的基线分离,其中甲烷-乙烷的分离度达到了2.23,与以介孔硅为固定相的微色谱柱相比提高了99%;甲烷、乙烷的峰面积以及甲烷-乙烷分离度重复性的相对标准偏差均小于3%.以上结果表明,以ZIF-8为固定相的微色谱柱在针对油田气实时分离的便携式微色谱系统中具有广泛的应用前景.A semi-packed column embedded elliptical cylindrical posts was fabricated based on micro-electromechanical system(MEMS),and metal-organic framework(MOF)material ZIF-8 was synthesized by hydrothermal method and coated on the inner wall of the micro channel as the stationary phase. The performance test is performed under constant temperature of 30 ℃. The micro gas chromatography(GC)column using ZIF-8 material as the stationary phase can achieve the baseline separation of the methane,ethane and propane(C1—C3)in 75 s,with the resolution between the methane and ethane of up to 2.23,99% higher than the micro GC column coated with mesoporous silica. The relative standard deviations of the peak areas of methane and ethane,and resolutions between methane and ethane were all less than 3%. The above results demonstrated the potential of the micro GC column using ZIF-8 as the stationary phase for use in portable analysis equipment for the real-time analysis of oil field gas.
