摘要: 本文在作者提出的反相液相色谱中同系物保留值与常沸点的交点规律基础上,推导出同系物保留值与流动相组成的交点规律,用大量实验数据作了检验。并用新交点方程式,由化合物在一个流动相组成下的保留值,预测该化合物在任一流动相组成下的保留值,对14组同系物在5种色谱柱上5类流动相下的验算结果表明,721个数据点的绝对平均误差为2.8%.

Abstract: Based on the intersection point rule for the retention value and normal boiling point of homologues in reversed-phase high-performance liquid chromatography,the intersection point rule for the retention value of homologues and mobile phase composition has been derived,and was testified by a lot of experimental data from the literature,With this newly proposed equation,we can use the retention value of the compound in one mobile phase composition to predict its retention value in any other mobile phase composition,For fourteen groups of homologues in five mobile phase on five kinds of columns,the overall average absolute error of 721 data sets is 2.8%.

Key words: Liquid chromatography, Retention value, Mobile phase composition, Intersection point rule
