Shodex RI-501 Refractive Index Detector

The Shodex RI-501 RID is a versatile and high sensitive RI detector that can be used with many HPLC system. It consists of a color-LCD, an automatic start-up function, and validation wizard. The detector series are available as Analytic, semi-micro and preparative line up.


  • The automatic start-up function controls the complicated operations such asblank substitution and baseline atabilization automatically.
  • The validation wizard enables easy component validation.
  • Improved double temparature control system shortens the required warm-up time and provides stable background.
  • The leak sensor automatically stops the pump in case of solvent leakage.
  • External input and output terminals and LAN (RJ45) communication ports can be used to connect various HPLC systems for an advanced automation.
  • Usable in UHPLC systems.
