SIELC Technologies has developed a new class of stationary phases, which provides three interactions with analytes:
Strong cation exchange interaction
Depending on analyte properties, one, two, or all three interactions can be applied to the separation.
This stationary phase facilitates the separation of structural isomers of aromatic compounds.
Additional pi-pi interaction creates a difference in the bind state for structural isomers and often resolves critical pairs of compounds. The degree of pi-pi interaction can be adjusted by varying the amount of acetonitrile in the mobile phase.
