Investigation of the stability of polyelectrolyte multilayer coatings in open‐tubular capillary electrochromatography using laser scanning confocal microscopy

Autor: Kapnissi‐Christodoulou, Constantina P., Lowry, M., Agbaria, R. A., Geng, L., Warner, I. M.

Publikováno v: Electrophoresis

A simple polyelectrolyte multilayer (PEM) coating procedure was used for the development of stable modified capillaries. PEM coatings were constructed in fused-silica capillaries using alternating rinses of cationic and anionic polyelectrolytes. The

Open-tubular capillary electrochromatography using a polymeric surfactant coating

Autor: Kamande, M. W., Kapnissi‐Christodoulou, Constantina P., Zhu, X., Akbay, C., Warner, I. M.

Publikováno v: Electrophoresis

A stable polyelectrolyte multilayer (PEM) coating was investigated for use in open-tubular capillary electrochromatography (o-CEC). In this approach, the PEM consisted of the cationic polymer of a quaternary ammonium salt, poly(diallyldimethylammoniu

Analytical separations in open-tubular capillary electrochromatography

Autor: Kapnissi‐Christodoulou, Constantina P., Zhu, X., Warner, I. M.

Publikováno v: Electrophoresis

This review represents a summary of recent progress in open-tubular capillary electro-chromatography (OT-CEC) for chiral and achiral separations. The OT-CEC approach is an alternative to packed-CEC that could eliminate the problems associated with re
