WebNov 30, 2016 · An indirect way of chiral analysis involves derivatization of the analyte, leading to two diastereomers followed by separation using traditional reversed-phase chromatography . Whereas, a direct method utilizes a chiral selector on chiral stationary phases (CSPs) (4– 10) or in the mobile phase to distinguish the enantiomers . WebHPLC requires freeze drying. Thus, dry-down is much faster and less expensive. The other major application, chiral purification, competes mostly against normal phase HPLC.
