HPLC

Definition

High-Performance Liquid Chromatography (HPLC) is an analytical technique used to separate, identify, and quantify components in a mixture. It leverages high pressure to push a liquid solvent through a column packed with solid particles, allowing for the effective separation of compounds such as polysaccharides and glycoconjugates based on their chemical properties.
