Abstract

Micro capillary columns were successfully applied to liquid chromatography by employing the principles used in micro high performance liquid chromatography. Fundamental investigations on the use of capillary columns in LC were performed for the various column parameters. Good separations of five aromatic hydrocarbons and four kinds of phthalic esters were obtained on a 62 ΞΌm I.D. capillary column, coated with SE‐30.

The experimental results are represented in Figure 1 ; as in ref. [5], the log k'and Csaxes have opposite directions. Although only few values of solubility are available, the variations of log kvalues and log CS values of 2-hydroxynaphthalenc? are clearly seen to be parallel; some deviations are
