Performance Specifications of the Agilent 1200 Series Binary Pump SL

Hydraulic system

Two dual piston in series pumps with proprietary

servo-controlled variable stroke drive, floating piston design

and active inlet valve

Setable flow range

Setpoints 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 measured with water

Pressure Operating range

0 – 600 bar (0 – 7800 psi) up to 5 ml/min

Pressure pulsation

Standard delay volume configuration < 2% amplitude

(typically < 1%)

Low delay volume configuration < 5% amplitude

(typically < 2%)

Compressibility compensation

Automatic, 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,

dependent on back pressure (includes 400 μl mixer)

Low delay volume configuration : 120 μl measured with water

Composition range

settable range

0 – 100%, recommended range: 1 – 99 % or 5 μl/min per channel, whatever is greater

Composition precision

< 0.15 % RSD at 1mL/min

Composition accuracy

± 0.35% absolute (water/caffeine tracer)
