Features:
- 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.
PC control and Chromatograph data processing system:
- Complete PC control function, realizing parameter control and real-time monitoring to all parts, including column oven.
- Interface language can be switched between Chinese and English, with simple operation.
- Analytical task can be completed in single sampling, with automatic processing of chromatograph data and obtaining perfect spectra.
- Backstage operation function enables data processing to the existing spectra, while analysis is going on.
- The gradient program of the pump and wavelength time-program of the detector can be established.
- The test report format can be flexibly modified.
- Timer turn-off function is provided.
