Highly sensitive refractive index detector for liquid chromatography.
ECOM spol. s r.o.
Part number

The Azura 2.1L Analytical Refractive Index Detector 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) and 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, high-pressure resistant flow cellimproved 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 Azura 2.1L Analytical Refractive Index Detector the perfect choice for most laboratory tasks.
This detector can be controlled with 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. Interface: 2 x LAN (RJ-45, dual IP-stack), USB (service only), multi-pin connector, analog (cinch connector)
