1290 Quaternary Pump

The 1290 Infinity Quaternary Pump is the only pump combining the ultimate performance of a binary low-pressure mixing UHPLC pump with the flexibility of a quaternary pump. The 1290 Infinity LC power range allows you to run any HPLC and UHPLC method. The Agilent InletWeaver guarantees highest mixing efficiency before the mobile phase enters the pump head. Active damping combines innovative pump engineering with tuning algorithms embedded in the firmware for reduced ripples and associated UV noise. Additional mixing capacity is achieved with the optional Agilent V380 Jet Weaver. A multipurpose valve adds useful functionalities, e.g. mixer in/out switch, filter back flush or automatic purge. BlendAssist software simplifies your workflow with accurate buffer/additive blending.

Features

  • Binary pump-like performance in terms of accuracy and precision for flow and composition. Read more       
  • Infinite power range combining ultrahigh pressure up to 1200 bar and high analytical flow rates up to 5 mL/min for maximum chromatographic performance       
  • Integrated high efficiency degasser with low internal volume is based on PTFE AF technology and offers fast change-over of solvents for purging and priming the pump       
  • Highest solvent mixing efficiency before reaching the pump head due to the new InletWeaver, based on established multilayer mixing technology       
  • Active damping with independently controllable high resolution pump drives and firmware-embedded tuning algorithms significantly reduce ripples and associated UV noise, switchable V380 Jet Weaver for extra mixing volume       
  • A multipurpose valve enables automatic software-embedded functionalities like switching the optional mixer in and out, flushing back the inline filter or automatic purging       
  • Convenient, precise and accurate buffer/additive blending using the new software feature BlendAssist, implemented in the pump driver.
