Refractive Index Detector : Shodex RI-501,502,504

Print

The Shodex RI-500 series is a versatile and high sensitive RI detectors that can be used with various manufactures '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.

(Features)
· 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.
