LC2200 binary high pressure analytical liquid chromatography gradient system Introduction
The whole system consists of high-pressure infusion pump, detector, injection valve, solvent tray, column, workstation software, etc. Installation, adjustment and use are very simple. This system is reliable in operation, easy to operate, and capable of meeting the general requirements of conventional laboratories. Features
1. Dual Wavelength Detection, Wavelength Time Program and Stop Pump Scanning - Three measurements minimize baseline noise and drift, achieving the highest sensitivity and lowest detection limits, as well as a wider linear range. Corresponding to various measurement requirements, the main components, by-products and impurities can be reliably quantified at the same time.
2.Independent mode design, one main pump controls other high-pressure infusion pumps of the same type, and the displayed gradient mode is verified by the gradient curve on the screen. Scalable to support 4-element high-pressure gradient systems.
3.Two-way solvent system to meet the needs of a variety of complex gradients, optimized analysis cycle and analysis capabilities, improved sensitivity, high throughput analysis capabilities, and excellent biocompatibility.
4.Floating plunger support structure, improve the service life of plunger and plunger seal, excellent durability and high infusion performance.
5.Microprocessor controlled, high speed dual drive and parallel pump heads with high chamber pressure feedback, compensated for refill and solvent compression for precise and highly reproducible flow rates over a wide dynamic range.
6.Quick and easy replacement of lamps and flow cells, and intelligent switching of tungsten lamps to ensure maximum uptime.
7.Intelligent knob panel design makes operation more convenient and intelligent. Technical Parameters
