Specifications 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

Settable flow range

Set points 0.001 - 5 mL/min, in 0.001 mlLmin 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 whatever is greater

Pressure operating range

0 - 600 bar (0 - 8700 psi) up to 5 mL/min

Pressure pulsation

Standard delay volume configuration:
< 2 %amplitude (typically < 1 %), at 1 mL/min isopropanol, at all pressures > 1 MPa
Low delay volume configuration:
< 5 %amplitude (typically < 2 %), at 1 ml/min isopropanol,
at all pressures > 1 MPa

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

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 1 mL/min

Composition accuracy

± 0.35% absolute

Control and data evaluation

Agilent ChemStation for LC, EZ Chrom Elite

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

Safety and maintenance

Extensive diagnostics, error detection and display (through Agilent LC Diagnostics), leak detection, safe leak handling, leak output signal for shutdown of pumping system. Low voltages in major maintenance areas.

Housing

All materials recyclable

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.
