Type |
Specification |
|
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 |
Set points 0.001 – 5 ml/min, in 0.001 ml/min increments |
|
Flow range |
0.1 – 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% of 10µl/min whatever is greater |
|
Pressure |
Operating range 0 400 bar (0-5880 psi) up to 5 ml/min |
|
Pressure pulsation |
< 2% amplitude (typically < 1%), at 1 ml/min isopropanol, at all pressures > 1 MPa |
|
Compressibility compensation |
User-selectable, 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 180-480 µl without mixer, 600 – 900 µl with mixer, dependent on back pressure |
|
Composition range |
1 – 99 % or 5 µl/min per channel, whatever is greater |
|
Composition precision |
<0.5% absolute |
|
Composition accuracy |
0.15% RSD, at 1 ml/min |
|
Control and data evaluation |
Agilent Chem Station for LC |
|
Analog output |
For pressure monitoring, 2mV/bar, one output |
|
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 handheld controllers G4208 A, G1323 B and Agilent Chem Station), leak detection, safe leak handling, leak output signal for shut down of pumping system. Low voltage in major maintenance areas |
|
GLP features |
Early maintenance feedback (EMF) for continuous tracking of instruments 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 |
