Agilent 1290 Infinity II High-Speed Pump

The 1290 Infinity II High Speed Pump uses high-pressure mixing for UHPLC gradient formation and solvent blending from up to two solvents at pressures up to 1300 bar and flow rates up to 5 mL/min.

The 1290 Infinity II High Speed Pump has an exceptionally low delay volume, which allows you to run ultrafast gradients for narrow-bore UHPLC applications. This capability makes this pump the ideal front-end for LC/MS applications. The full ISET range allows you to seamlessly transfer existing methods from different instruments, including current Agilent systems as well as instruments from other manufacturers.

Features:

• Power range combines ultrahigh pressure up to 1300 bar and high analytical flow rates up to 5 mL/min for maximum UHPLC performance
• Lowest delay volumes down to 10 µL allow you to run ultrafast gradients on narrow-bore columns, making this pump the ideal front-end for LC/MS applications
• Intelligent System Emulation Technology (ISET) enables emulation of existing Agilent 1100, 1200, and 1260 Infinity Series instruments, as well as Waters Alliance, Waters H-Class, and Shimadzu Prominence instruments facilitating seamless method transfer
• Active damping with independently controllable high-resolution pump drives and firmware-embedded tuning algorithms significantly reduce ripples and associated UV noise
• Multipurpose valve enables automated software-embedded functionality such as switching the optional mixer in and out, flushing back the inline filter or automated purging for reduced manual interaction
• Jet Weaver mixer, based on multilayer microfluidic technology, combines highest efficiency mixing with lowest delay volume for highest UV-detector sensitivity
• Integrated high-efficiency degasser with low internal volume is based on PTFE AF technology and provides for fast change-over of solvents for purging and priming the pump
• Built-in active seal-wash increases instrument uptime
