The paper demonstrates that the technique of solvent generated liquid‐‐solid chromatography can be used to create normal phase systems for chiral separations. The chiral adsorption layer was generated by pumping a binary hexane:ethanol eluent containing a small fraction of permethylated β‐cyclodextrin through a column packed with microparticulate silica. This technique leads to columns with good time stability and reproducibility. The possibility of generating normal phase systems with permethylated β‐cyclodextrin as chiral component via the mobile phase broadens the range of phase system which can be used to separate enantiomers by HPLC.
