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. |
