毛细管气相色谱法具有高效和快速的特点,如混合物组分不太多,难分离物质对的α值又不是太小(如不小于1.05),使用短毛细管色谱柱可使分析时间显著缩短。前一报告[1]曾用短毛细管柱分离二、三硝基甲苯异构体取得成功。本文进一步用两支短OV-225毛细管柱分离并测定几种二元取代 Capillary gas chromatography has the characteristics of high efficiency and fastness. For example, the composition of the mixture is not too large, the alpha value of the hardly separated substance pair is not too small (for example, not less than 1.05), and the analysis time can be shortened using the short capillary column. The previous report [1] used short capillary column separation of TNT isomers successfully. In this paper, two shorter OV-225 capillary columns were further used to separate and determine several binary substitutions
