AZURA Detector DAD 6.1L
Article No.: ADC11

Diode array detector

The AZURA DAD 6.1L is a high-end diode array detector (DAD) which combines outstanding performance with easy handling. A wide range of easily exchangeable flow cells make this device the right choice for fast, standard analytical, semi-preparative and preparative separations with bio-compatible or stainless steel wetted parts. State-of-the-art total reflection flow cells (LightGuide technology) are available for this detector providing maximum light throughput (due to total internal reflection) with minimal peak dispersion (due to small cell volume) to guarantee an optimized signal to noise (S/N) ratio. An optional fiber optics adapter offers the possibility to separate the flow cell spatially from the device and thus provides enhanced security for hazardous, explosive or toxic work processes, as well as protecting the device from leakages at high flow rates. The newly developed optical unit with KNAUER Polka-Dot technology and intelligent temperature management ensure maximum sensitivity combined with minimal baseline drift over the whole spectrum. Furthermore, easy frontal access and improved safety features enable effortless lamp replacement. This eases maintenance and guarantees short downtimes. The DAD 6.1L comes installed with a high brightness deuterium and tungsten halogen lamps, which cover a wavelength range from 190 to 1000 nm. This detector can be controlled with OpenLab® EZChrom Edition, ClarityChrom®, Chromeleon® and PurityChrom® software, as well as from the Mobile Control software (stand-alone operation), via LAN or through analog input/output, allowing it to be integrated into almost any LC system.
