The capacity factors k' of eight thiazole derivatives on reversed-phase ODS column with methanol/water as eluant were measured, the linear regression between the lnk'values and methanol concentrations according to equation lnk'=a+cCb was carried out and a good linear relationship was obtained. The parameters a and c with various concentrations of methanol as eluant were measured. ln addition, the effect of various salts and triethylamine on the capacity factors of thiazole derivatives were studied. A mobile phase of methanol: 0. 2 mol/L HAc-NaAc buffer solution (pH 4. 0): triethylamine=45: 54: 1 and UV detection at 254 nm brought about satisfactory results.
