The AZURA MWD 2.1L is an 8 channel, sensitive multiwavelength detector combining high performance with easy handling at an affordable price. A wide range of easily exchangeable cartridge flow cells make this device the right choice for fast, standard analytical, semi-preparative and preparative separations with bio-inert or stainless steel wetted parts. State-of-the-art total reflection flow cells (LightGuide technology) are available for this device providing maximum light throughput (due to total internal reflection) with minimal peak dispersion (due to the small cell volume) to guarantee an optimized 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 and intelligent temperature management ensure for maximum sensitivity combined with minimal baseline drift. Furthermore, easy frontal access and improved safety features enable effortless lamp replacement. This eases maintenance and guarantees short downtimes. This device is also easily upgradable to a diode array detector. The MWD 2.1L comes installed with a deuterium lamp which covers a wavelength range from 190 to 700 nm. This detector can be controlled with OpenLab® EZChrom, 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.
