摘要：

Significant selectivity differences between semi-polar capillary gas chromatographic columns involving the elution order of acyclic and polycyclic lipid molecules have been observed. These differences occur despite these columns being reported to be ''equivalent'' in catalogue specifications. In Part I, the changes in retention indices between columns manufactured by different companies were described. In this paper, it is shown that these variations in selectivity may even be observed among semi-polar columns originating from the same manufacturer.
