High-End Diode Array Detector for Liquid Chromatography and Process Technology

Designed for highest sensitivity through innovative light mixing technology

The AZURA DAD 6.1L is a high-end diode array detector with a wavelength range from 190 to 1000 nm. The large selection of flow cells makes it the ideal choice for all liquid chromatography and process applications. It combines excellent performance with easy handling. The AZURA DAD 6.1L is the right choice with its optional fiber optic adapter and the flexibility related to this feature. Especially for applications that require high flow rates or special safety precautions, this adapter and the physical separation from the flow cell means safety. Due to the innovative optical unit with the KNAUER polka-dot technology, the detector offers maximum sensitivity. This makes it ideal for trace analysis. The intelligent temperature management enables fast operational readiness after startup. It also minimizes baseline drift. Due to the frontally accessible deuterium and halogen lamp, the device is easy to service. The downtime is thereby reduced to a minimum if a lamp replacement is necessary. For analytical applications, the AZURA DAD 6.1L is controlled by software packages OpenLab® EZChrom Edition, ClarityChrom®, and Chromeleon®. The PurityChrom® software is also available in the field of purification. The control in the process environment can be implemented via a spring strip, analog outputs, and the Mobile Control.
