Polyethers in inorganic capillary electrophoresis

摘要: Abstract Various additives are employed in running solutions capillary electrophoresis (CE) to enhance separation performance and selectivity. Complexing agents successfully (in most cases indispensable) inorganic CE, especially for the of metal ions. Studies analytical chemistry have been mostly directed methodological developments analyses transition ions, extensive efforts permitted development a number effective reagents their determination. Thus, there numerous forming complexes with In contrast, ligands effectively complexing main group cations very few. Polyethers rather unique examples such capable interacting hard cations. this naturally leads designs where polyethers incorporated solution CE achieve better separations another interesting feature which is also potentially useful separation; polyether–water mixtures provide electrophoretic media, allow one modify selectivity much more than usual organic solvents. review, author discusses roles from two different viewpoints, (1) complex formation (2) medium modifiers, perspectives these compounds CE. Some new data presented show ability as modifiers.
