Abstrakt:	In the present study, a comparison was performed between chiral stationary phases (CSPs) prepared by coating or covalent immobilization of cellulose tris(3-chloro-5-methylphenylcarbamate) onto silica. The columns were evaluated in HPLC separation of enantiomers of various acidic, basic, and neutral chiral analytes in acetonitrile, methanol, and mixtures of n-hexane and propan-2-ol as mobile phases. A difference in enantiomer-resolving ability of coated and covalently immobilized CSs was observed. [ABSTRACT FROM AUTHOR]
