Performance Specifications of the Agilent 1260 Infinity Binary Pump (G1312B)
Specification
Two dual piston in series pumps with
servo-controlled variable stroke drive,
power transmission by gears and ball
screws, floating pistons
Set points 0.001 – 5 mL/min, in
0.001 mL/min increments
0.05 – 5.0 mL/min
≤0.07 % RSD or ≤0.02 min SD, whatever is
greater
± 1 % or 10 µL/min, what ever is greater
Operating range 0 – 60 MPa (0 – 600 bar,
0 – 8700 psi) up to 5 mL/min
< 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)
Low delay volume configuration:
< 5 % amplitude (typically < 2 %)
Pre-defined, based on mobile phase
compressibility
1.0 – 12.5, solvents with pH < 2.3 should
not contain acids which attack stainless
steel
High-pressure binary mixing
Standard delay volume configuration:
600 – 800 µL, (includes 400 µL mixer),
dependent on back pressure
Low delay volume configuration:
120 µL
settable range: 0 – 100 %
recommended range: 1 – 99 % or
5 µL/min per channel, whatever is greater
Comments
based on retention time at
constant room temperature
pumping degassed H
