Microemulsion electrokinetic chromatography (MEEKC) was introduced to evaluate the hydrophobicity of various kinds of compounds. Using a separation solution consisting of sodium dodecyl sulfate (SDS), 1-butanol, heptane, and a borate-phosphate buffer, the logarithm of the capacity factors, which is proportional to the free energy of transfer into the microemulsion, was highly correlated with the logarithm of the octanol/water partition coefficients (log Pow) rather than with that of the SDS micelle/ water partition coefficients measured by micellar electrokinetic chromatography. Even for compounds with hydrogen bond accepting or donating sites, the correlation
