The enantiomeric separation of several 2-arylpropionic acids has been
studied by capillary isotachophoresis using two chiral selectors added
to the leading electrolyte with the aim to find the optimum experimen
tal conditions for qualitative purpose. Enantiomeric resolution was re
corded for fenoprofen, flurbiprofen, ibuprofen and ketoprofen, when he
ptakis(2,3,6-tri-O-methyl)-beta-cyclodextrin was used as additive in t
he leading electrolyte.
