Refractive Index Detector: Shodex RI-201
(Features)
· A nobel optical system (three-chamber flow cwll) provides at least twice the sensitivity of our previous detectors.
· The double temperaturefluctuations.
· The limit of detection for saccharides is approximately 2 ng.
Prenciple of New optical system measurement
in our previous optical system, the measurement light through the flow cell was refracted onlr once. the new three-chamber flow cell allows the light to be refracted wice, thereby inceasing sensitivity at least tow-times at the same optical path length. this doubles the defection degree and results in not only reduces the noise half, but reduces the drift caused by optical systems half.

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.
