LC-2212 High Performance Liquid Chromatograph Introduction
The LC2100 high performance liquid chromatograph is a very cost-effective precision instrument. The whole machine components are imported and assembled. The technical indicators and the quality and reliability of the products have reached the domestic leading level. Some performance indicators are even better than those of foreign countries. The same kind of products of the brand, the instrument is easy to operate and can realize computer control. features
1.The pump head self-flushing function, the pump can be infused without manual emptying;
2.Using the "floating pump plunger rod seal" technology, the life of the seal can be extended, and the liquid is not leaked for 5000 hours;
3. Programmable solvent-based compression factor, which can be automatically compensated;
4.Complete pump types: analytical, semi-preparative and preparative;
5.UV-Vis detector uses advanced holographic concave grating and dual optical path design, the detection wavelength can be extended to the visible spectrum range;
6.It is easy to replace the flow cell for daily maintenance;
7.MCU control technology, the instrument has a higher automation and self-test function, all parameters are operated by the keyboard;
8.Advanced circuit design with excellent optical path structure, the detector has very low noise and baseline stability;
9.The cumulative ignition time and number of ignitions of the xenon lamp can be automatically calculated;
10.All parameters can be protected from power failure;
11.Adopt the 7725i injection valve to ensure high reliability and reproducibility of the instrument;
12.The modular structure is designed to be easily extended to a gradient elution system. Technical Parameters
