High Performance Liquid Chromatography, Base unit pump (HPLC)




<br />



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.
