Table 4 Performance Specification Agilent 1260 Infinity Quaternary Pump VL (G1311C)
Type Specification
Hydraulic system Dual piston in series pump with proprietary servo-controlled variable stroke drive,
floating pistons
Setable flow range 0.001 – 10 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 H
2
O at 10 MPa
Pressure Operating range 0 – 40 MPa (0 – 400 bar, 0 – 5880 psi) up to 5 mL/min
Operating range 0 – 20 MPa (0 – 200 bar, 0 – 2950 psi) up to 10 mL/min
Pressure pulsation < 2 % amplitude (typically < 1.0 %), or < 3 bar at 1 mL/min isopropanol, at all pressures
> 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 proprietary high-speed
proportioning valve
Delay volume 600 – 900 µL, dependent on back pressure
Composition range 0 – 95 % or 5 – 100 %, user selectable
Composition precision < 0.2 % RSD, at 0.2 and 1 mL/min
Control and data evaluation Agilent control software
Analog output For pressure monitoring, 2 mV/bar, one output
Communications Controller-area network (CAN), RS-232C, APG Remote: ready, start, stop and
shut-down signals, LAN optional
