    Notes: A new “push/pull” model has been developed to explain synergistic effects observed in a system in which a chiral stationary phase (CSP) is used in combination with its homologous chiral mobile phase additive (CMPA). The model predicts the beneficial CMPA enantiomer and the counterproductive CMPA enantiomer a priori. Thus, an (R)-CSP will obtain positive synergism from a homologous (S)-CMPA and negative synergism from a homologous (R)-CMPA. The reverse is true for an (S)-CSP. The importance of structural homology between the CSP and the CMPA is demonstrated. Furthermore, the analysis time is decreased relative to the use of a CSP alone, because the retention time of the analyte peaks decreases when the CMPAs are used. © 1993 Wiley-Liss, Inc.
