high-performance liquid chromatography
Quick Summary
High-performance liquid chromatography (HPLC) is a powerful technique used in chemistry to separate, identify, and quantify components within a mixture. It utilizes a liquid mobile phase that is pumped at high pressure through a column packed with a stationary phase.123
The separation occurs as different substances in the mixture interact with the stationary phase to varying degrees. Components that interact more strongly with the stationary phase move more slowly through the column, while those with weaker interactions travel faster. This difference in migration time allows for the separation of complex mixtures. HPLC is versatile and can be used to analyze a wide range of compounds, including inorganic ions, amino acids, drugs, and proteins.32
