Deirdre Cabooter on Method Development in UHPLC: Performing ultrahigh-performance liquid chromatography (UHPLC) can significantly reduce analysis time without compromising on efficiency by using sub 2-μm particles that allow increased velocity while maintaining selectivity. In this new short interview, Deirdre Cabooter of KU Leuven in Belgium, discusses the advantages of using UHPLC in method development and tips to follow when transferring methods from UHPLC to HPLC instrumentation.
