The Multifaceted Diode Array Detector AZURA® DAD 2.1L from KNAUER

The KNAUER AZURA DAD 2.1L diode array detector with innovative cartridge flow cell design covers an extensive application range from nano to process scale liquid chromatography (LC).

By means of straightforward and swift flow cell exchange, this detector can be optimized within seconds for highly sensitive analytical UHPLC/HPLC or for in-line detection at high flow rates (> 10 L/min). State-of-the-art total reflection flow cells (LightGuide technology) are available for this device providing maximum light throughput with minimal peak dispersion. Flow cell types and materials are available for HPLC, biochromatography (FPLC) and for other flow-through applications.

Remote Flow Cells

With the aid of a world-first fiber optics adapter in cartridge design, the flow cell can be spatially separated from the device up to 10 m. Key applications of this remote flow cell technology include enhanced security for explosive, radioactive or toxic applications; detection at high temperatures (100 °C); and flexible flow cell installation. The latter can be useful to minimize system dead volume between column and detector or in multiple detector setups. Frontal access and improved safety features enable effortless lamp replacement for easy maintenance and short downtimes.

Flexibility of Control

The AZURA DAD 2.1L detector can be controlled with OpenLab^® EZChrom Edition, ClarityChrom^® and PurityChrom^® Bio and even more software packages. Direct control is possible from an optional Mobile Control app for windows tablet or PC. Connection via LAN or analog signals allows easy integration into almost any LC system.
