Specification |
Hydraulic System |
Two dual piston in series pumps featuring a proprietary servo-controlled variable stroke drive, floating piston design, and active inlet valve. |
Settable Flow Range |
Set points from 0.001 to 5 ml/min with increments of 0.001 ml/min. |
Flow Range |
0.1 to 5.0 ml/min. |
Flow Precision |
<0.07% RSD or <0.02 min SD (whichever is greater), based on retention time at constant room temperature. |
Flow Accuracy |
±1% of 10µl/min, taking the greater value. |
Pressure |
Operating range of 0 to 400 bar (0-5880 psi) up to 5 ml/min. |
Pressure Pulsation |
<2% amplitude (typically <1%) at 1 ml/min isopropanol across all pressures above 1 MPa. |
Compressibility Compensation |
User-selectable according to mobile phase compressibility. |
Recommended pH Range |
1.0 to 12.5, with a caution that solvents with pH <2.3 should not contain acids that can corrode stainless steel. |
Gradient Formation |
High-pressure binary mixing with a delay volume of 180-480 µl without a mixer, and 600-900 µl with a mixer, depending on back pressure. |
Composition Range |
1% to 99% or 5 µl/min per channel, whichever is greater. |
Composition Precision |
<0.5% absolute. |
Composition Accuracy |
0.15% RSD at 1 ml/min. |
Control and Data Evaluation |
Compatible with Agilent Chem Station for LC. |
Analog Output |
For pressure monitoring, providing 2mV/bar for one output. |
Communications |
Utilizes controller-area network (CAN), GPIB, RS-232C, and includes remote ready, start, stop, and shutdown signals, with optional LAN compatibility. |
Safety and Maintenance |
Equipped with extensive diagnostics and error detection capabilities, including leak detection and safe handling protocols. Features low voltage in key maintenance areas. |
GLP Features |
Includes early maintenance feedback (EMF) for real-time monitoring of instrument usage, seal wear, and pumped mobile phase volume, with user-settable limits and feedback messages. Maintains electronic records of maintenance and errors. |
Housing |
Made from recyclable materials. |
