Prediction of chiral separation of ketoprofen using experimental design

Abstract

The paper demonstrates how experimental design could be applied to predict chiral resolution and run time for indirect chiral high performance liquid chromatography (HPLC) analysis of ketoprofen. An attempt is made to establish quantitative relationship between chromatographic variables and the response factors (resolution and retention time). The effects of important chromatographic variables on chiral resolution and retention time have been highlighted by way of interaction studies. This technique enables optimal utilization of resources by avoiding trial and error approach. The study advocates that experimental design is a prospective tool to predict and optimize chromatographic conditions for chiral HPLC analysis.
