Stability of capillaries coated with highly charged polyelectrolyte monolayers and multilayers under various analytical conditions--application to protein analysis.

The stability of capillaries coated with highly charged polyelectrolytes under various analytical conditions was studied, as well as their performance for the analysis of proteins by Capillary Electrophoreis (CE) over a wide range of pH (2.5-9.3). In this study, fused silica capillaries were modified either with a poly(diallyldimethylammonium) chloride… CONTINUE READING
