High Performance Liquid Chromatograph (Isocratic with auto sampler) - PFL2200-2

High Performance Liquid Chromatograph

Special features:

Double beam monochromator, dual lens flow cell, pursue superelevation

sensitivity.

Uses the import D₂lamp,solar battery, 1200 /mm concave raster

composition's double beam monochromator, precision work's double lens wind

through the pond, high accuracy microprocessor control wave length adjustment, two-circuit high speed sampling's 24 A/D,has guaranteed detector's low noise, the low drifting and the superelevation sensitivity, the setoff import similar instrument level.

Original creative pressure feedback control system, maximum limit reduces the system dead volume

Uses the advanced pressure feedback control system, abandoned the dead
volume big pipeline mixer, not only reduced the flow path dead volume greatly, also because of the pressure feedback speed change technology's use, enhanced the pump flux stability.

Unique online cleaning function, guarantees the instruments durability
and easy to maintain

Unique online plunger rod clean function, may establish
the time sequencing to realize the self-cleaning, because prevented the buffer salt separation to cause the plunger rod enormously the attrition and in mobile phase extremely micro adsorbate in the pump head's accumulation, guarantees the instruments steady operation.

Building block type combination, many kinds of separations,examination pattern

Many kinds of separation examination pattern, isocratic separation pattern,gradient separation pattern,time flux procedure separation

pattern,single wave length examination pattern,stops flow wave length scanning examination pattern and the time wave length procedure examination pattern.

Ultra strong control function, intellectualized supervisory system, have
functions instrument self-checking,self-adjustment etc.

Ultra strong instrument control function, covered has managed from the
flowing to the chromatograph analytical data report output entire control,
conformed to the GLP standard instrument quality authentication function,
guaranteed the analytical data accuracy,reliability, so long as were joined to
the auto sampler, establishment corresponding procedure then realized the
unattended LC analysis.

Include one high pressure solvent delivery pump, one ultraviolet-visible
spectrophotometer detector, one manual valve or auto sampler,one liquid
chromatograph column,one reverse control or control chromatography
workstation,one column oven.Is suitable applies in QA/QC.,conventional material content analysis.

High Pressure Binary Gradient Liquid Chromatograph System

Include dual high pressure solvent delivery pump(built-in binary gradient
mixer), one ultraviolet-visible spectrophotometer detector, one manual or auto sampler,one liquid chromatograph column,one reverse control chromatography workstation,one column oven.Is suitable in the scientific research,chromatograph condition exploration,complex sample analysis, impurity examination etc.

Quaternary Low-pressure Gradient Liquid Chromatograph System

Include one quaternary low-pressure binary solvent delivery pump, one
ultraviolet-visible spectrophotometer detector, one manual or auto sampler,one liquid chromatograph column,one reverse control chromatography workstation,one column oven.Is suitable in routine gradient analysis,each kind of analysis method development,as well as needs many kinds of solvent gradients sample.
