This Agilent 1260 Infinity HPLC System is a complete modular liquid chromatography platform for routine and advanced analytical applications. The configuration combines a G1311B Quaternary Pump, G1329B Standard Autosampler with G1330B Thermostat, G1316A Thermostatted Column Compartment, and G4212B Diode Array Detector. Together, these modules provide flexible four-solvent gradient formation, automated and temperature-controlled sample handling, precise column temperature control, and simultaneous chromatographic and UV/Vis spectral detection.
