Refractive Index Detector for high performance liquid chromatography
RI-500series

概要

For the detection of samples that are not UV absorption!

Available in 3 different configurations!

RI-500series

Features

  • Improved double temperature control system shortens the required warm-up time and provides stable background.
  • A relief valve is installed in order to protect the solenoid valve.
  • The leak sensor automatically stops the pump in case of solvent leakage.
  • Connectable to each company's HPLC system.

RI-501(Analysis type)

  • RI-501 can be used with conventional HPLC

Baseline stabilization is improved compared with existing products!

High reproducibility is observed on repeated measurements!

Consecutive analysis of Monosaccharides and Disaccharides using Shodex SUGAR SP0810

RI-501graph

  • Column: Shodex SUGAR SP0810
  • Eluent: H2O
  • Flow rate: 0.5 mL/min.
  • Column temp.: 80 ℃

RI-504(Semi-micro type)

  • RI-504 has small cell and internal volume, creating higher resolution and higher efficiency.
  • The eluent consumption is decreased to less than 50 % versus the conventional type.
