Agilent 1200 Series - G2226A HPLC Nano Pump, Agilent Technologies (CAT#: STEM-C-0078-LGZ)

The manufacturer of Agilent 1200 Series - G2226A HPLC Nano Pump is Agilent Technologies. Model is 1200 Series - G2226A. The Agilent 1200 Series NanoFlow Pump utilizes unique solvent delivery technology optimized for nanoliters per minute flow with active feedback and real-time flow Regulated EFC (Electronic Flow Control) function. EFC is the gold standard for robust and reliable nanofluidic performance, providing precise flow and gradient performance, which is essential for high-sensitivity nanospray mass spectrometry performance while maintaining time reproducibility and stable ion generation.

Condition: used
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.

1. Electronic traffic control (EFC) can adjust the flow rate in real time during the entire analysis process to obtain reliable and reproducible results.
2. The internal volume of very low internal volume of the micro vacuum per channel (1 mL) for fast changeover of mobile phase and quick purge.
3. Handheld controller control to convenient local status monitoring.
4. Second -generation traffic sensor.
5. Application focus: high -resolution separation and high sensitivity mass spectrometry detection. Protein group is a typical application area for nano -flow pumps.
