Agilent 1290 Infinity Binary Pump (G4220A), Agilent Technologies (CAT#: STEM-CPO-0889-ZJF)

The manufacturer of the Agilent 1290 Infinity Binary Pump (G4220A) is Agilent Technologies.
The Agilent 1290 Infinity Binary Pump (G4220A) comes refurbished and delivers the industry’s widest analytical power range for ultimate chromatographic performance and flexibility. Lowest delay volumes allow you to run ultra fast gradients for narrow-bore applications. Active damping combines innovative pump engineering with tuning algorithms embedded in the firmware for significantly reduced ripples and associated UV noise. Background noise is reduced further by the Agilent Jet Weaver mixer, which is based on multi-layer technology.

Condition: Pre-owned
Hydraulic system: Two dual pistons in series pumps with proprietary servo-controlled variable stroke design, power transmission by ball screws, smooth motion control of pistons for active damping.
Settable Flow Range Setpoints: 0.001—5 ml/min, in 0.001 ml/min increments. Executed in 300 pl/step increments.
Flow Precision: ≤0.07 % RSD or 0.005 min SD, whatever is greater (0.2—5.0 ml/min). Based on retention time at constant room temperature.
Flow accuracy: ±1 % or 10 µl/min, whatever is greater. Pumping degassed H2O at 10 MPa (100 bar)
Pressure operating range: Operating range up to 120 MPa (1200 bar), up to 2 ml/min, 80 MPa(800 bar) at 5 ml/min.
Pressure pulsation: <1 % amplitude or < 0.5 MPa (5 bar), whatever is greater. At 1 ml/min water
Compressibility: compensation Automatic, pre-defined, based on mobile phase selection.
Gradient formation: High pressure binary mixing.
Delay volume: Jet Weaver V35: <45 µl Jet Weaver V100: <75 µl JetWeaver generally recommended. For applications requiring lowest delay volumes, JetWeaver can be removed out of the flow path. Delay volume is then solely determined by the volume of the connection capillary.
Composition range: Settable range: 0 – 100 % Recommended range: 1 – 99 % or 5 µl/min per channel
