| Popis: | 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. |
