Analysis of Lignans Using Micellar Electrokinetic Chromatography

, 2009
Micellar electrokinetic chromatography (MEKC) was used to separate twelve lignan compounds originating from Phyllanthus plants. To increase the reliability of peak identification, two micellar systems, the sodium dodecyl sulfate (SDS) and sodium ...

Retention indices in micellar electrokinetic chromatography [PDF]

, 1997
The use of retention indices in micellar electrokinetic chromatography (MEKC) is evaluated both from a theoretical and a practical point of view. Fundamental equations for the determination of retention indices in MEKC are described, showing that ...

Gradient micellar electrokinetic chromatography.

SEIBUTSU BUTSURI KAGAKU, 2008
A Surfactant gradient method was developed for miceller electrokinetic chromatography (MEKC). In the present method, electroosmotic flow was suppressed almost completely and thus, micelles in a running solution of the inlet vial were introduced in turn into the capillary during operations.

Liquid Chromatographic and Capillary Electromigration Techniques for the Analysis of Azole Antifungals

Journal of Separation Science, Volume 48, Issue 4, April 2025.
ABSTRACT Since the introduction of azoles as antifungals in 1979, they gradually gained a spotlight in both medicinal and industrial fields. Other than being the leading antifungal medicinal drug agents, azoles have also been a major pesticide in agricultural industry.
