High-performance liquid chromatography (HPLC) is a powerful analytical technique used to separate, identify, and quantify components in a mixture. This method utilizes high-pressure pumps to force solvents through a column filled with stationary phase material, allowing for precise separation of compounds based on their interactions with the stationary phase. In radiochemistry, HPLC plays a crucial role in separating radioactive isotopes and analyzing complex samples while ensuring regulatory compliance and quality control.
