High performance liquid chromatography is characterized by high efficiency and rapid separation, and is widely used for the analysis of large molecules or unstable compounds in fields such as chemical engineering, biology, pharmaceuticals, pesticides, food, and environmental protection.

Instrument composition:

• 757 Variable wavelength UV detector
• 757P constant flow pump
• Chromatographic data processor (or chromatographic workstation)
• Injection valve
• chromatographic column

Instrument features: This system is the most basic liquid phase system configuration, with high quality, low price, and easy operation. Its performance meets the needs of routine analysis.

Main component technical indicators:

1. Working pressure of constant flow pump: 1-40Mpa Flow range: 0.01-99.99ml/min Flow setting accuracy and repeatability: better than 1% (based on pure water) Pressure pulsation:<0.15Mpa

2 Variable wavelength UV detector working range: 195-600nm wavelength accuracy: ± 2nm measurement range: 0.01-2.56 (AU) sample cell volume: 8ul noise: ± 2 * 10^-5AUFS baseline drift: 2 * 10^-4AUFS/H

3 injection valve maximum pressure: 35Mpa quantitative tube volume: 6-way 10UL-2ml

Choose one chromatographic column for 4 columns

5. Selection of Chromatographic Data Processing Machine or Chromatographic Workstation
