HPLC chromatography system CH-LC-4000

UV

UV Series Intelligent All-controlled Liquid Chromatography System consists of PT501 high-pressure constant-current pump and CH-LC- 4000 UV detector. which directly form isocratic analysis systems and gradient analysis system. Its workstation can simutaneously control several sets of CH-LC-4000 high-pressure constant-current pumps, CH-LC-4000 UV detectors and constant-temperature column boxes, etc. to realize multiple high-pressure gradient washing. wavelength scanning and other functions. This system is both intuitive and convinient to operate. Users can imput ail of the control information through a small keyboard inside the instrument with the opération process displayed on the LCD screen even if it is not connected with a computer. It can also be connected with a computer to use the workstation software. Pure digital communications are used between the workstation and chromatography, reading second channel sampling data directly without any treatmen or signal distortion, thus ensures sampling précision and post- treatment without loss of data. Its sampling accuracy can amounts to 20 (0.1 seconds / time* 2 channels). Workstation can alter the wavelength, the pump flow rate, the deuterium lamp switch, hence users can stop the pump at any time or switch the steering pump valve to let components remain in the flow cell, and then automatically start the wavelength scanning to obtain a continuous spectrum of the components on différent wavelengths. As the software is running in WINDOWS system with ail the functions menulized. users feel easy to operate it without special training.
