High performance liquid chromatography

High performance liquid chromatography

Application:

It is widely applied to biochemistry, food analysis in various fields, medical research, environmental analysis and inorganic analysis.

Detail:

High performance liquid chromatography (HPLC) is also known as high pressure liquid chromatography, high speed liquid chromatography, high resolution liquid chromatography. HPLC requires that the sample can be made only solution compated with the sample pretreatment. With high resolution, high sensitivity, high speed, column can be repeatedly used, the outflow component is easy to collect, etc., microcontent elements can be separated. The main types include liquid-solid adsorption chromatography, liquid-liquid partition chromatography, bonded phase chromatography, gel chromatography.

Feature:

1. The system by the high-pressure pump, UV detector, injector valves, solvent tray, columns, working software and other components; installation, commissioning and use are very simple.

2. High-pressure infusion pump adopts CPLD technology, high-precision infusion pump system controlled by a microcontroller. Full digital frequency generation system, friendly human-machine display interface, advanced motor drive systems, advanced pump head and single valve design make the system under all conditions is guaranteed accuracy and repeatability of the infusion.

3. UV is a spectroscopic detector, it can match any infusion pumps, and have a wide range of applications. Uses a fully digital, highly integrated design, greatly reduce the noise of the instrument; based on digital signal transmission and processing,  the detector signals can be input directly into the computer's serial port for acquisition.
