High-Performance Liquid Chromatography (HPLC) is a powerful analytical technique used for the separation, identification, and quantification of components in complex mixtures. Its principle is based on the differential interactions of analyte molecules with a stationary phase and a mobile phase, allowing separation based on chemical properties such as polarity, charge, and molecular size. The stationary phase is typically a finely divided solid or a chemically bonded phase packed into a column, while the mobile phase is a liquid solvent or a mixture of solvents that carries the sample through the column. Separation occurs because different compounds in the mixture interact with the stationary phase and the mobile phase to different extents, resulting in distinct retention times for each component as they elute from the column. The fundamental principle underlying HPLC is chromatographic partitioning, which may involve adsorption, partitioning, ion exchange, or size exclusion, depending on the column type. In reversed-phase HPLC, the stationary phase is non-polar, usually a C18-silica bonded phase, and the mobile phase is relatively polar, which causes polar compounds to elute faster while non-polar compounds are retained longer. In normal-phase HPLC, the stationary phase is polar, _____ ____ _______ ______ ____.
