Description
Specifications:
- 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: Setpoints 0.001 – 5 ml/min, in 0.001 ml/min increments
- Flow range 1 – 5.0 ml/min
- Flow precision: <, 0.3 % RSD (typically 0.15 %), based on retention time, at 1 ml/min
- 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: 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
