Specification |
|
Hydraulic system |
Dual plunger in series pump with proprietary servo-controlled variable stroke drive, floating plungers and active inlet valve |
|
Setable flow |
0.001 – 10 ml/min, in 0.001 ml/min increments |
|
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 |

|
Pressure pulsation |
pulsation < 2 % amplitude (typically < 1 %), at 1 ml/min is opropanol, at all pressures > 1 MPa (10 bar) |
|
Compressibility compensation |
User-selectable, based on mobile phase compressibility |
|
Recommended pH |
1.0 – 12.5, solvents with pH < 2.3 should not contain acids which attack stainless steel |
|
Gradient formation |
Low pressure quaternary mixing/gradient capability using proprietary high-speed proportioning valve Delay volume 800 – 1100 µl, dependent on back pressure |
|
Composition Range |
0 – 95 % or 5 – 100 %, user selectable |
|

Agilent control software (e.g. Chem Station, EZ Chrom, OL, etc.) |
|
Communications
|
Controller-area network (CAN), GPIB, RS-232C, APG Remote: ready, start, stop and shut-down signals, LAN optional |
|
Safety and maintenance
|
Extensive diagnostics, error detection and display (through control module and Agilent Lab Monitor & Diagnostic Software), leak detection, safe leak handling, leak output signal for shut down of pumping system. Low voltages in major maintenance areas. |
|
GLP features
|
Early maintenance feedback (EMF) for continuous tracking of instrument usage in terms of seal wear and volume of pumped mobile phase with user-settable limits and feedback messages. Electronic records of maintenance and errors. |
|
Housing |
All materials recyclable |
