The Agilent 1200 Infinity Binary Pump G1312B is well suited to fast gradient separations where low delay volume and precise solvent composition are critical. In standard configuration, the pump uses a mixer and pulse damper, while bypassing both reduces pump delay volume to approximately 120 µL. This makes the system particularly useful for fast methods using 2.1 mm ID columns and applications requiring minimal gradient delay.
