RI Refractive Index Detector RID100 - preparative

analytical Differential Refractometer

  

For semi-preparative and preparative HPLC 

With wide linear dynamic range and 100 ml/min
maximum flow rate

  




These competively priced refractive index detectors are characterized by fast baseline stabilization, high sensitivity and excellent reproducibility. The highly pressure resistant flow cell, the long-life LED and optimized safety components guarantee minimal maintenance and easy handling.

The differential refractometer are used for detecting compounds with little or no UV activity, such as sugars, alcohols, lipids or polymers in high concentration. The detectors can be operated in stand-alone mode or be integrated in different LC-systems.

Performance characteristics

  • extremely pressure-stable measuring cell
  • long-life LED
  • tempered optical unit
  • improved safety components (with leak sensor)
  • large linear measuring range
  • maximum flow rate of 100 ml/min
  • easy handling and operation
  • minimal maintenance
  • stand-alone mode or integration in LC systems
  • made in Germany

Range of uses

For example, for the detection of:

    *  saccharides
    *  organic acids
    *  proteins
    *  peptides
    *  polymers
    *  lipids
