High Performance Liquid Chromatography, Base unit pump (HPLC)
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.
