Agilent 1200 Series G2226A Nano LC Pump

Agilent 1200 Series G2226A Nano LC Pump
Agilent 1200 Series G2226A Nano LC Pump



Hydraulic system

Two dual piston in series, with proprietary servo-controlled variable

stroke drive, floating piston, active inlet valve, solvent selection valve

and electronic flow control for flow rates from 0.1 to 1 µl/min

Settable column flow range

0.01 – 4 µl/min

1 – 2500 µl/min (with the electronic flow control bypassed)

Recommended column flow range

0.1 – 1 µl/min

200 – 2500 µl/min (with the electronic flow sensor bypassed)

Optimum composition range

1 to 99% or 5 µl/min per channel (primary flow), whatever is greater

Composition precision

< 0.2 % SD, at 500 nl/min (default settings),

Minimum primary flow/pump channel is 5 µl/min

Delay volume

Typically 300 nl from the electronic flow control to the pump outlet for flow rates up to 4 µl/min. For flow rates up to 4 µl/min and electronic flow control active: primary flow path 180 - 480 µl; system pressure dependent (default settings; calculated volume) Typically 180 to 480 µl (system pressure dependent) for flow rates up to 2.5 ml/min. (default settings; calculated volume)

Pressure range

20 to 400 bar (5880 psi) system pressure

Compressibility compensation

User-selectable, based on mobile phase compressibility

Recommended pH range

1.0 – 8.5, solvents with pH < 2.3 should not contain acids which attack stainless steel. Upper pH range is limited by fused silica capillaries.

Control and data evaluation

Agilent ChemStation for LC

Analog output Communications

For pressure monitoring, 2 mV/bar, one output

Controller-area network (CAN), GPIB, RS-232C, APG Remote: ready, start, stop and shut-down signals, LAN optional

Control and data evaluation

Agilent control software (e.g. Chem Station, EZ Chrom, OL, etc.)

Safety and maintenance


Extensive diagnostics, error detection and display (through control module and Agilent ChemStation), leak detection, safe leak handling, leak output signal for shutdown of pumping system. Low voltages in major maintenance areas.

GLP features


Early maintenance feedback (EMF) for continuous tracking of instrument 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.



All materials recyclable.
