Web1. sep 2024 · Phenyl columns (Figure 2a) can interact with aromatic compounds by π-π interaction, where an electron is transferred from the solute to the phenyl group. Cyano columns can also interact with electron donors by π-π interaction (Figure 2b), and in addition the strong dipole of the cyano group can attract the dipoles in very polar solutes (Figure 2c).
WebIn addition, the phenyl column displayed better separation of later-eluting impurities, such as the 17mer impurity. The mass-overloaded injections resulted in classical Langmuirian elution profiles on all columns, provided the concentration of the ion-pairing reagent in the eluent was sufficiently high. ...
