The Agilent 1100 G1311A Quaternary Pump ensures virtually
pulse-free and stable solvent flow, with dual floating pistons in series,
precisely servo-controlled. This design with variable stroke volume allows
pulse-free solvent delivery and efficient mixing. An inlet-valve electronically
activated and synchronized to piston stroke eliminates vapor formation with
volatile solvents and is maintenance free. The Agilent quaternary pump is
equipped with a high-speed proportioning valve.
