The retention behaviour and separation ability of normal and reversed phase HPLC with one non-polar and two polar mobile phases, have been studied by measuring the retention constants of a series of newly synthesized 1,2,4-triazole derivatives. The results are discussed in terms of the nature of the solute, eluent and stationary phase.

The separation ability and retention of normal and reversed phase HPLC with, respectively, three non-polar and two polar mobile phases, have been studied by measuring the retention constants of a series of newly synthesized estrone derivatives. The separation ability and retention are discussed in terms of the nature of the solute, eluent and stationary phase. Good correlation was found between the retention constants log k0 of newly synthesized estrone derivatives obtained on C-18 column and log P calculated by different methods.

The effect of C-18 silica gel surface coverage on the retention behaviour of some estrone derivatives in reversed phase high performance liquid chromatography has been studied. Two commercial columns with different C-18 coverage, Spherisorb ODS-1(8 % carbon content) and Li Chrosorb RP-18(22% carbon content), using methanol-water as the eluent, were used.
