ABSTRACT

   A simple methodology for preparing synthetic multiple-interaction (SMI) chiral stationary phase (CSP) column is described in this report, The column was synthesized by an in situ derivatizing procedure and can be easily prepared with a standard analytical HPLC set-up. The column is a no frills, low cost one, and can be tailored to various packing particle sizes and column lengths. The efficiency of the column is high; over 5,000 plates per 10 cm Applications on resolving some racemic drugs in plasma and formulation are illustrated.

Key words : Chiral stationary phase, Enantiomers resolution, Column preparation
