Agilent HPLC (High-Performance Liquid Chromatography) systems are advanced analytical instruments used for separating, identifying, and quantifying compounds in a mixture. Manufactured by Agilent Technologies, these systems are widely used in pharmaceuticals, environmental testing, food safety, and chemical research. Agilent HPLCs are known for their high precision, reliability, and user-friendly software (such as OpenLab or ChemStation). Common models include the Agilent 1100, 1200, and 1260 Infinity series.
