Liquid chromatography (LC) is a separation technique in which the mobile phase is a liquid. Liquid chromatography can be carried out either in a column or a plane. Present day liquid chromatography that generally utilizes very small packing particles and a relatively high pressure is referred to as high performance liquid chromatography (HPLC).
High-performance liquid chromatography (or high-pressure liquid chromatography, HPLC) is a chromatographic technique that can separate a mixture of compounds, and is used in biochemistry and analytical chemistry to identify, quantify and purify the individual components of the mixture.
Instrument Introduction
Skl-2200-II high performance liquid chromatograph was the luck sets up the company to synthesize the SKL-2200 high performance liquid chromatograph's manufacturing experience, promoted the reverse control series high performance liquid chromatograph according to the market demand, had perfect GLP management system, high accuracy PC control, advanced structural design, outstanding performance, provided the best solution for yours laboratory.
Instrument Specification:
Double beam monochromator, dual lens flow cell, pursue superelevation sensitivity.
Uses the import D2 lamp,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.
