    SY-8100 High Performance Liquid Chromatograph

    DESCRIPTION

    1¡¢Scientific and reasonable function and structure design satisfy your needs for accuracy and reproducibility to the maximum.

    2¡¢Building-block modular design enables easy use and convenient maintenance.

    3¡¢Rich function PC control and chromatograph data processing software make it simple for instrument control and data processing.

     

    INNOVATION

    1¡¢High pressure solvent delivery pump adopting electronic pulsation suppression technology displacing traditional mechanical buffer to thoroughly solve the problem caused by frequent leakage of mechanical buffer, and to reduce the dead volume of solvent delivery system to the minimum.

    2¡¢The wavelength positioning of Multi-wavelength UV-Vis detector is realized via the grating¡¯s turning which is directly controlled by the SCM(Single Chip Micyoco).  It takes place the conventional sine-pole mechanism (monochromator), eliminating the error of wavelength positioning brought by the mechanical abrasion and returning error of the Guide-screw transmission, and also avoiding the monochromator¡¯s hitting accident which might be brought by false operation.
