The separation of the isomers of dimethylpyridine has been studied by
capillary electrophoresis. Studies at low pH where the dimethylpyridin
es all bear the same charge showed a partial separation probably due t
o size/shape effects. The charge profiles of the analytes calculated f
rom their ionisation constants were compared with their separation bet
ween pH 2.5 and 9. The optimum resolution was found at a pH of 6.5 in
the area of maximum charge difference between the dimethylpyridines.
