liquid chromatography system fast protein liquid chromatography system MS:1003593 MS A system for Fast Protein Liquid Chromatography (FPLC), a versatile and widely used medium-pressure chromatography technique primarily employed for the separation and purification of biomolecules, especially proteins. It operates under low to moderate pressures, making it suitable for labile proteins and other large biomolecules that might be denatured by the high pressures and organic solvents often used in high-performance liquid chromatography.
