HPLC Liquid chromatograph LC1620A
The use of a floating plunger support mechanism improves the service life of the plunger and plunger sealing ring.
Introduction of CAN bus (i.e. controller local area network)
Automatic operation, reverse control workstation, and system settings can be completed on a computer.
In addition to conventional UV detectors, the LC1620A can also be configured with a differential refractive detector and an evaporative light scattering detector.
Features
Plunger rod online cleaning function: The high-pressure constant flow pump adopts a double sealing ring design to clean buffer salts, reduce wear of key components, and extend service life.
Flow monitoring function: real-time monitoring of the mobile phase, dual warning design, when the set value is reached, the system will give an alarm or automatically stop the pump, effectively protecting the HPLC system.
Three measurement methods: dual wavelength detection, wavelength time program, and pump stop scanning can correspond to different measurement requirements.
