Imad Haidar Ahmad and colleagues at Merck present multifactorial peak crossover (MPC)—a new technique to quickly isolate peaks of interest. Using computer-assisted chromatographic modelling, the separation landscape is mapped and conditions that change peak-elution orders are found. Peaks of interest can be quickly shifted to convenient areas of the chromatogram, dramatically reducing the time spent...

This article describes a simple approach for the development and implementation of an efficient ultra-high performance liquid chromatography (UHPLC) assay that is extensively applied to the separation and analysis of multicomponent reaction mixtures of closely related pharmaceutical intermediates and impurities. ACD/LC Simulator was used in conjunction with multi-column and multi-solvent UHPLC screening to optimize methods.
