The book is about the technology and application of Mixed-mode chromatography (MMC). Unlike conventional single-mode HPLC, which resolves the analytes primarily based on their ionic or hydrophobic properties, MMC employs multifunctional stationary phases to exploit at least two modes of interactions (i.e., ionic and hydrophobic) with the analytes and as such often provides resolution that far exceeds that observed with a single-mode process. Over the past two decades, MMC has developed into an important analytical and purification tool in a number of applications in pharmaceutical and...
