text: The chiral stationary phase, CSP, can interact differently with two enantiomers, by a process known as chiral recognition. Chiral recognition depends on various interactions such as hydrogen bonding, π-π interaction, dipole stacking, inclusion complexation, steric, hydrophobic and electrostatic interaction, charge-transfer interactions, ionic interactions etc, between the analyte and the CSP, to form in-situ transient-diastereomeric complexes.
  Most of the types of stationary phases can be classified as Pirkle type (Brush type), Protein-based, Cyclodextrins based, Polymer-based carbohydrates (polysaccharide-based CSPs), Macrocyclic antibiotic, Chiral crown ethers, imprinted polymers, etc.
