Highly sensitive refractive index detector for liquid chromatography
Analytical refractive index detector
The AZURA RID 2.1L is a sensitive and competitively priced differential refractometer. It is suitable for detecting compounds with little or no UV activity such as alcohols, sugars, lipids or polymers. This instrument is designed for use in analytical HPLC (high performance liquid chromatography) as well as under certain conditions for GPC (gel permeation chromatography) applications. The intelligently designed optical unit with advanced temperature control ensures high sensitivity, fast baseline stabilization, and excellent reproducibility. Furthermore, the long-life LED, highly pressure resistant flow cell, improved safety features and enhanced diagnostics functions guarantee easy handling and minimal maintenance. The wide linear dynamic range, its low internal volume of 43 µl from the inlet to the flow cell and 10 ml/min maximum flow rate make the AZURA RID 2.1L the perfect choice for most laboratory tasks. This detector can be controlled with OpenLAB® EZChrom, ClarityChrom®, Chromeleon® and PurityChrom® Bio software, as well as from the AZURA Mobile Control app (stand-alone operation), via LAN or through analog input/output, allowing it to be integrated into almost any LC system.
