Specifications – Agilent 1260 Infinity Quaternary Pump
Specifications Agilent 1260 Infinity Quaternary Pump (G1311B) and VL version (G1311C)
Hydraulic system Dual piston in series pump with servo-controlled variable stroke drive, floating pistons.
Settable flow range Set points 0.001 - 5 mL/min, in 0.001 mL/min increments.
Flow range 0.2 - 10.0 mL/min
Flow precision ≤ 0.07 % RSD or ≤ 0.02 min SD, whatever is greater; based on retention time at constant room temperature.
Flow accuracy ± 1 % or 10 μL/min whatever is greater; pumping degassed H2O at 10 MPa (100 bar).
Pressure operating range 1260 Infinity Quaternary pump:
Operating range up to 60 MPa (600 bar, 8700 psi) up to 5 mL/min
Operating range up to 20 MPa (200 bar, 2950 psi) up to 10 mL/min
1260 Infinity Quaternary pump VL:
Operating range up to 40 MPa (400 bar, 5880 psi) up to 5 mL/min
Operating range up to 20 MPa (200 bar, 2950 psi) up to 10 mL/min
Pressure pulsation
< 2 % amplitude (typically < 1.3 %) or < 0.3 MPa (3 bar), whatever is greater, at
1 mL/min isopropanol, at all pressures > 1 MPa (10 bar, 147 psi).
Compressibility compensation User selectable, based on mobile phase compressibility.
Recommended pH range 1.0 - 12.5, solvents with pH < 2.3 should not contain acids which attack stainless steel.
Gradient formation Low pressure quaternary mixing/gradient capability using high-speed proportioning valve.
Delay volume 600 – 900 μL, dependent on back pressure; measured with water at 1 mL/min (water/caffeine tracer).
Composition range 0 - 95 % or 5 - 100 %, user selectable.
Composition precision < 0.2 % RSD or < 0.04 min SD, whatever is greater, at 1 mL/min; based on retention time at constant room temperature.
Integrated degassing unit Number of channels: 4
Internal volume per channel: 1.5 mL
Materials in contact with solvent: TFE/PDD Copolymer, FEP, PEEK, PPS
Control Agilent control software (e.g. ChemStation, EZChrom, OL, MassHunter).
Local control Agilent Instant Pilot
Communications Controller-area network (CAN), RS-232C, APG Remote: ready, start, stop and shut-down signals, LAN optional.
Safety and maintenance
Extensive diagnostics, error detection and display through Agilent LabAdvisor, leak detection, safe leak handling, leak
output signal for shutdown of the pumping system. Low voltage in major maintenance areas.
GLP features Early maintenance feedback (EMF) for continuous tracking of instrument usage in terms of seal wear and volume of
pumped mobile phase with pre-defined and user settable limits and feedback messages. Electronic records of
maintenance and errors.
