1 Description

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

Building-block modular design enables easy use and convenient maintenace.

Rich function PC control and chromatograph data processing software makes it simple for instrument control and data processing.

2 Innovation

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.

The wavelength positioning of Multi-wavelength UV-Vis detector is realized via the grating's turning which is directly controled by the SCM( Single Chip Micyoco).  It has taken place the conventional sine-pole mechanics (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.
