RI-500 系列


Refractive Index Detector 

 * RI-500 詳細資訊 *

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-uptime 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.
