Abstract
The influence of alcohol modifiers with different chain length on the migration time window in micellar electrokinetic chromatography (MEKC) has been studied. Highly polar alcohols like methanol and 1‐propanol are typical aqueous phase modifiers. Higher alcohols like 1‐butanol, 1‐pentanol and 1‐hexanol influence the micellar structure and are considered as micellar phase modifiers. The effect of long chain alcohols is small because of their low applicable concentrations.
