Application


  • Separation of cresols using coelectroosmotic capillary electrophoresis.: This research explores the separation of cresol isomers using coelectroosmotic capillary electrophoresis. The study demonstrates an efficient method for analyzing cresol mixtures, which is valuable in both industrial and pharmaceutical applications where precise separation of isomers is critical (Masselter et al., 1993).
