Gradient HPLC 1620

  • High Performance Liquid Chromatography

    Superior high-pressure pump achieves accurate solvent delivery with high-precision and low-fluctuation.

    Advanced and innovative design modules provide high reliability and accuracy for long time operation.
    The pump works in-parallel and ensures accuracy and duration.
    Different kind of detectors, including UV/VIS detector and refractive index detector etc. provide stronger detection capability and more options.
    Pumping system: Isocratic system and gradient system.
    UV Detector for routine analysis/ RID for universal detection in isocratic analysis, especially necessary in GPC system.



    A truly effective HPLC

    All maintenance parts are accessible from the front panel for quick replacement without disassembling instrument

    The monitoring system will stop the pump if pre-limit pressure is exceeded
    All components are controlled intelligently through workstation
    Multiple data analysis functions, flexible peak identification and data management, etc
