Chromatography Flashcards Quizlet

High performance liquid chromatography (HPLC) Column chromatography that involves the stationary phase being a column tightly packed with silica gel beads or alumina beads with high surface area. It uses a solvent, which is constantly flowing through the column, as the mobile phase and it carries the liquid sample through the column and out.
