Diode Array Detector

The Thermo Scientifc Dionex UltiMate 3000 Rapid Separation Diode Array Detector (DAD-3000RS) is the detector of choice if you need maximum flexibility in your laboratory. It offers reliable UV-vis detection for both conventional and rapid separation LC applications with full wavelength spectra acquisition, sub-1 nm pixel resolution, and data collection rates up to 200 Hz. 

  • Low noise (typically <±7 μAU) and drift (typically <0.5 mAU/h) for lowest LODs and LOQs
  • Data collection rates of up to 200 Hz allow detection and characterization of even the sharpest peaks
  • Full UV-vis spectra data acquisition even for 10 peaks separated in 10 s
  • Stainless steel and PEEK flow cells provide maximum application flexibility
  • Front access to prealigned cells and lamps simplifies routine maintenance
  • ID chips for tracking of lamp and cell parameters in audit trails

The DAD-3000RS features eight channels of single-wavelength data acquisition, a 1024 element diode array, and excellent noise and drift performance close to forward-optic detectors. The comprehensive set of 3D data tools in the Thermo Scientifc Dionex Chromeleon Chromatography Data System software makes it easy to process and report your data.

The Thermo Scientific Dionex UltiMate 3000 PCM-3000 pH and Conductivity Monitor is an upgrade for accurate pH and conductivity on-line monitoring with the DAD-3000 Series. A typical application area of this unit is monitoring the gradient formation in salt- or pH-gradient-based ion-exchange chromatography (IEC) in biopharmaceutical analysis.

Note: A standard version, DAD-3000, with a data rate of up to 100 Hz is also available for use in combination with UltiMate 3000 analytical systems.
