摘要： 通过对色谱分离过程的热力学处理, 得到了用毛细管色谱法测定溶质在溶剂中的溶解热力学性质的关系式, 利用该式测定了硝基氨基甲苯的五种异构体在SE-30, SE-54固定液中的溶解焓和溶解熵, 并对结果进行了定性解释。

Abstract: A equation between the thermodynamic properties and the retention values of capillary gas chromatography was proposed. The thermodynamic properties of nitromethylaniline isomers on cros3linking SE-30, SE-54 and noncrosslinking SE-54 fused silica capillary columns have been calculated and the results were interpreted qualitatively.

Key words: Capillary gas chromatography, Nitromethylaniline isomers, Retention value
