Chiral interactions in capillary zone electrophoresis: computer simulation and comparison with experiment.
Chiral interaction in capillary electrophoresis can be modeled using pK values, mobilities of analytes, and their formation constants with the chiral selector. An existing steady-state simulation program for CE (HPCESIM) was recently extended with a chiral submenu involving the chiral parameters listed above. These were experimentally determined in both our laboratories for mandelic acid and terbutaline using hydroxypropylated beta-cyclodextrin as chiral selector. A comparison was made between both sets of parameters and between experimental electropherograms and those obtained from simulation. Error analysis of the results indicate the sensitivity of the obtained results.
