Refractive Index Detector: Shodex RI-101, 102, 104
The Shodex RI-100 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.
(Features)
· Equipped with a color liquid crystal display, the detector monitors s in real time.
· The automatic start-up function controls the complicated operations such asblank substitution and baseline atabilization automatically.
· The validation wizard enables easy component validation.
· Improved 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 RS232C communication ports can be used to connect various HPLC systems for an advanced automation.
