High-Performance Liquid Chromatography (HPLC) is a specialized analytical technique used to separate, identify, and quantify components in a sample. It involves the passing of a liquid sample through a column packed with stationary phase material that interacts with the components in the sample, leading to their separation. HPLC requires the use of specialized equipment and skilled technicians to perform the analysis and interpret the results. This technique is widely used in various fields, including pharmaceuticals, food science, environmental science, and forensic science.
