Mobile Phase Modifiers for HPLC and LC/MS

High Performance Liquid Chromatography (HPLC) is one of the most common instrumental techniques for analyzing mixtures of organic compounds in analytical labs around the world. HPLC is a complex process that depends on each molecule’s ability to interact with the mobile phase that carries it through the column, the solid phase that fills the columns, as well as interactions between the different molecules in the sample.
