采用液相沉渍法制备出高效Al2 O3/SPLOT毛细管色谱柱 ,并采用Al2 O3/SPLOT柱对C1 ～C4 低碳烃和聚合级丙烯试样进行了分析。结果表明 ,所制备的Al2 O3/SPLOT柱具有较高的柱容量、适宜的选择性、良好的柱惰性 ,其对C1 ～C4 低碳烃具有较强的分离能力。柱与柱之间的重复性好
High performance Al 2 O 3 / SPLOT capillary columns were prepared by liquid immersion method. The samples of C1-4 C4 hydrocarbons and propylene polymerization grade were analyzed by Al2 O3 / SPLOT column. The results showed that the prepared Al 2 O 3 / SPLOT column has high column capacity, suitable selectivity and good column inertness, and has strong separation capability for C1-C4 low-carbon hydrocarbons. Repeatability between columns is good
