The inlet system in Figure 1 proved to be efficient for injecting a wide-bore fused silica column with a lipid solution. The column inlet liner was instrumental in trapping most of the fat thus preventing the small amount of packing material and retention gap from becoming grossly contaminated. The
## Abstract In aqueous capillary electrophoresis the electroosmotic flow (EOF) can be strongly suppressed or eliminated by coating the capillary surface silanols either by buffer additive adsorption or chemical modification. Hydrophilic coatings, __e.g.,__ polyvinyl alcohol (PVA) proved to be most
One can increase the residence time of analytes in a capillary electrophoresis experiment by reducing the electroosmotic flow. Such measures increase separation efficiency and resolution. It is possible to accomplish this by hydrostatic backflow but dispersion induced by the parabolic flow profile c
