摘要: Abstract Electrolyte composition is critical in optimizing separation and detection of ions by capillary electrophoresis. The parameters which must be considered when designing an electrolyte system for electrophoresis include electrophoretic mobility constituents analytes, mode, compatibility with one another. An based on pyromellitic acid well suited use indirect photometric detection, provides excellent separations anions. ability to modify the as a function ph flexibility matching mobilities analytes. Additionally, alkyl amines electroosmotic flow modifiers allows rapid anions reversing direction fused-silica capillary. optimization anion analysis also discussed terms pH, ionic strength applied voltage. effect organic solvent selectivity discussed.
