| Abstract: | With sodium dodecyl sulfate(SDS)/n-hexane/n-butanol/tetraborate microemulsion as running buffer in capillary electrophoresis chromatography,the variation of electroosmotic flow(EOF) in different pH conditions have been discussed with the methanol peak as the EOF in this microemulsion system.The effect of pH value on the microstructure of the microemulsion system by determining particle sizes and zeta potential of microdroplets was studied,and effect of pH value on the interaction between micro droplets was ... |
