Analytical Refractive Index

The Smartline RI detector 2300 is a competitively priced differential refractometer suitable for detecting compounds with little or no UV activity such as sugars, lipids or polymers. The instrument is designed for use in analytical HPLC (high performance liquid chromatography) as well as for GPC (gel permeation chromatography) applications. This detector can be controlled with OpenLab® EZChrom, ChromGate® and ClarityChrom® software via RS-232, as well as from the front panel (stand-alone operation), as well as through analog input/output; allowing it to be integrated into almost any LC system. Delivery includes a 15 µl flow cell.
