Tabl e 2 Performance Specifications of the Agilent 1260 Infinity Binary Pump (G1312B)
Type Specification Comments
Hydraulic system Two dual piston in series pumps with 
servo-controlled variable stroke drive, 
power transmission by gears and ball 
screws, floating pistons
Setable flow range Set points 0.001 – 5 mL/min, in 
0.001 mL/min increments
Flow range 0.05 – 5.0 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, what ever is greater pumping degassed H
2
O at 
10 MPa (100 bar)
Pressure operating 
range
Operating range 0 – 60 MPa (0 – 600 bar, 
0 – 8700 psi) up to 5 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 > 
1MPa (10bar, 147psi)
Low delay volume configuration:
< 5 % amplitude (typically < 2 %) 
Compressibility 
compensation 
Pre-defined, 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 High-pressure binary mixing
Delay volume Standard delay volume configuration:
600 – 800 µL, (includes 400 µL mixer), 
dependent on back pressure
Low delay volume configuration:
120 µL
measured with water at 
1 mL/min (water/caffeine 
tracer)
Composition range settable range: 0 – 100 %
recommended range: 1 – 99 % or 
5 µL/min per channel, whatever is greater
