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. Sampling split system and ultraviolet visible detector constitute this machine.
LC-200 HPLC adopts microcomputer high pressure infusion pump with two complementary pumps and self-examine system. The materials of the pump are stainless steel or Polymer Materials.Ultraviolet visible detector uses Grating system. Specially --made Micro-- flowing cell can set time-varying wavelength analyze. The terminal device is five inches colored LCD which can observe the results of the observed testaments and spectrogram; it can also function as the inputting window for the operation parameters.The international used standard six-way valve is chose as the sample injector; the materials of the connect cannula is stainless steel or PEEK cannula; separator column use standard C18 column; The instrument has a column thermostat, the case can install two 70mm-250mm column tubules at the same time. The canuals, joint washers and Spindle Adapters used in the analyze system are all meet the international requirements. It can share the out porting signals with the import instruments. It has data processing machine interface (1AU/V) and recorder interface (10mV/FS) and equipped with RS232 output interface which can cooperate with chromatographic working station to achieve two-way alternate communication control.
