Jkyp-1 liquid chromatograph

Main performance characteristics:
1. The pump head has a self flushing function, allowing for infusion without the need for manual emptying;
2. Adopting the "floating pump plunger rod sealing ring" technology can extend the life of the sealing ring and prevent leakage for 5000 hours;
3. Programmed solvent compression factor that can automatically compensate;
4. Complete pump types: analytical, semi prepared, and prepared;
5. The UV visible light detector adopts a holographic concave grating and dual optical path design, and the detection wavelength can be extended to the visible spectrum range;
6. Easy to replace the flow cell, convenient for daily maintenance;
7. The microcontroller control technology enables the instrument to have high automation and self checking functions, and all parameters are operated by the keyboard; 8. The circuit design, combined with excellent optical path structure, enables the detector to have low noise and baseline stability;
9. Automatically calculate the cumulative ignition time and number of ignitions of tritium lamps;
10. All parameters can be protected against power failure;
11. Adopting the 7725i injection valve from Rheodyne Corporation in the United States to ensure high reliability and reproducibility of the instrument;
12. Building block structure design, easy to expand into gradient elution system.
