text: An interesting way of achieving chiral distinction on a CSP is the use of selectors with chiral cavity. These chiral selectors are attached to the stationary phase support material. In this category, there are basically three types of cavity chiral selectors namely cyclodextrins, crown ethers and macrocyclic glycopeptide antibiotics. Among these cyclodextrin based CSP is popular. In this type of CSPs the enantioselective guest-host interaction governs the chiral distinction.
