选用碳分子筛作吸附剂 ,用液相沉淀法涂渍出高效PLOT碳分子筛石英毛细管色谱柱 ,并对其色谱性能进行了考察。结果表明 ,该色谱柱具有良好的分离特性 ,1次进样可分离出O2、N2、CO、CO2、CH4、C2H2、C2H4、C2H6 等组分;适用于炼厂气、烟道气、水煤气及变压器油溶解气等的分析。 The carbon molecular sieve was selected as adsorbent, and the high performance PLOT carbon molecular sieve quartz capillary column was coated by liquid phase precipitation method. The chromatographic properties were also investigated. The results show that the column has good separation characteristics. One injection can separate O2, N2, CO, CO2, CH4, C2H2, C2H4, C2H6 and other components; suitable for refinery gas, flue gas, water gas and Transformer oil dissolved gas analysis.
