The Shodex RI-100 series includes versatile and highly sensitive RI detectors equippd with a color liquid crystal display, an automatic start-up function, and a validation wized, and can be used with various HPLC systems.
- Equipped with color liquid crystal display, the detector monitors status of chromatograph in real time.
- The automatic start-up function automates complicated operations such as the substituting eluent in the reference cell and checking the baseline stabilization.
- The validation wizard achieves component validation with ease.
- Optimization of the temperature control method shortens the time for stabilization after the start-up and improves baseline stavility.
- The leak sensor automatically stops the pump in case of solvent leakage.
- External input and output terminals and RS232C communication ports permit advances automation of the system.
