UV-VIS Detector

The Thermo Scientific Dionex UltiMate 3000 VWD Rapid Separation Variable Wavelength Detectors are the detectors of choice for routine chromatography applications. They offer high sensitivity, low noise and drift, and a wavelength range of 190–900 nm. The VWD is available in two variants. The standard version (VWD-3100), with a 100 Hz data rate, is economically affordable for laboratories on a limited budget. The rapid separation version (VWD-3400RS) offers a data rate of up to 200 Hz to perfectly detect even the narrowest peaks. Both detectors are designed to meet the demanding requirements of today’s laboratories.

  • Low noise (typically < ±2.5 µAU) and drift (< 0.1 mAU/h) guarantee high sensitivity
  • Linear range of up to 2.5 AU allows for the analysis of a wide range of analyte concentrations [more
  • Easily adaptable detector allows use with HPLC applications from nanoprepartive through to semipreparative HPLC
  • Data collection rates of up to 200 Hz allow detection of even the sharpest peaks
  • Predictive performance technology continually monitors system performance and warns of impending errors such as lamp failure.
  • Spectrum scanning functionality for analyte characterization

The PCM-3000 pH and Conductivity Monitor is an upgrade for accurate on-line pH and conductivity monitoring with the VWD-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.

The VWD-3400RS is ideal for any UHPLC application in single wavelength mode. For conventional LC applications, the detector allows data acquisition of up to 4 UV-vis channels up to 5 Hz. The VWD-3100 is ideal for use with
UltiMate 3000 analytical systems. Both detector variants support wavelength scanning  for method development or analyte characterization.
