Agilent 1100 Binary Pump (G1312A)
Lowest volume capillary connections - two dual-piston, in-series pumps in one housing for a minimum of bench space and lowest internal and external volume. Only 180 - 480 µl internal volume (without mixer).
Low flow - starting at typically 50 µl/min for reproducible gradients at low flow with solvent degassing.
Reliable design - with electronically-controlled active inlet-valves for flow rates up to 5.0 ml/min, the pump is also ideally suited to standard-bore chromatography. Floating pistons with path-of-least-resistance principle ensures highest seal lifetime.
Flow Precision: <0.3 % RSD (typically <0.15 % RSD)
Flow Range: Setpoints from 0.001 to 5.0 ml/min, in 0.001 ml/min increments
Operating range: 0 - 40 MPa (0 - 400 bar, 0 - 5880 psi)
Pulsation: <2 % amplitude (typically <1 %) at 1 ml/min isopropanol at all pressures >1 MPa (> 10 bar, >147 psi)
Compressibility compensation: User selectable, based on mobile phase compressibility
Delay volume: 180 - 480 µl (600-900 µl with mixer) dependent on back pressure
Recommended pH range: 1.0 - 12.5. Solvents with pH <2.3 should not contain acids which attack steel
GLP Features: Electronic records of maintenance and errors.
Early maintenance feedback (EMF) for
continuous tracking of instrument usage, display of feedback messages if preset limits are exceeded.
