The k’ (capacity ratio)and w_(1/2) (width at half peak height) values of chromatographic peaks were measured for the members of three homologous series, i.e. n-alkanes, n-alkyl alcohols and n-alkyl benzencs on three packed columns with OV 22,5, EGS or PEG 4000 as liquid phase respectively under suitable chromatographic conditions. It was found that the k’-w_(1/2) points of any homologous series on any column did not fall into a straight line, while they were best fitted by a curve.When the method of linear regression was applied to the k’-w_(1/2) data in order to make a comparison with the results of other chromatographers, it was proven that the linear regression lines obtained on the same column for samples of different homologous series always differed significantly.Whether β, a column parameter proposed by Lu, the author who advanced the theory of multi-component chromatography, may hold constant was also experimentally tested, and it was concluded that the constancy of β found little experimental The k ’(capacity ratio) and w - (1/2) (width at half peak height) values ​​of chromatographic peaks were measured for the members of three homologous series, ie n-alkanes, n-alkyl alcohols and n-alkyl benzencs on three packed columns with OV 22,5, EGS or PEG 4000 as liquid phase respectively under suitable chromatographic conditions.
