May 26, 2020 · High-performance liquid chromatography (HPLC), also known as high-pressure liquid chromatography, is an advanced type of LC. HPLC is amenable to a wide range of applications, such as pharmaceuticals and food analysis. It is especially useful for low or non-volatile organic compounds, which cannot be handled with gas chromatography.
