摘    要:根据色谱热力学理论,在色谱保留值公式统一形式的基础上导出了气相色谱保留系数(I)与反相液相色谱保留公式参数a,c之间的关系式,证明结构类似化合物的a,c值与保留指数呈线性关系,同时存在氢键作用能、偶极矩作用的影响,从而提出了色相色谱与反相液相色谱保留值换算的方法;该理论为氯代芳烃的文献数据所证实。

关 键 词:气相色谱  液相色谱  保留值  换算方法  色谱热力学

Abstract:According to chromatographic thermodynamic theory from the unified form of retention equations the relationship of retention index I of gas chromatography with retention equation coefficients a and c of liquid chromatography has been deduced. It is found that there exists a linear relationship of I with a and c in compounds similar in struture, but effects of hydrogen bond energy and dipole moment should be considered. Thus a method of conversion between gas chromatographic and reversed _ phase chromatographic retention values was suggested. Those formulas were confirmed by experimental data in references on chlorobenzols.
Keywords:Gas chromatography  Liquid chromatography  Retention value  Conversion
