摘　　要：A new equation describing the relationship between the retention values of homologues and column temperature, carbon numbers, mobile phase composition in reversed-phase liquid chromatography, has been inferred on the basis of the basic equation or chromatogram reten.tion value proposed by Lu Peizhang et al. [1] Mathematical method and experiment data have proved that there is a common point of intersection for the straight lines or in k. vs. T-1 in,the homologues when chromatogram column and mobile phase composition have been determined in reversed-phase liquid chromatograpby. Therefore, the intersection point equation has been put forward and examined by experimental data, and the results are satisfactory.A new equation describing the relationship between the retention values of homologues and column temperature, carbon numbers, mobile phase composition in reversed-phase liquid chromatography, has been inferred on the basis of the basic equation or chromatogram reten.tion value proposed by Lu Peizhang et al.
