Waters 2489 UV/Visible Detector

Whether performing routine UV-based applications or pushing the limits of detection with low-level impurity analyses, Waters 2489 UV/Visible (UV/Vis) Detector is the best detection choice for function, performance, and reliability. The 2489 UV/Vis Detector is the most sensitive and adaptable dual-wavelength absorbance detector available for HPLC. The design combines a high energy Deuterium source, a precise optical design, and low noise, high speed electronics.  These advanced capabilities take UV/Vis detection performance to a new level.

Flow Cell:

  • 1000 psi Max Pressure
  • 70 bars Max Pressure
  • HPLC Analytical 10mm


  • Enhanced sensitivity via patented TaperSli flow cell, which channels light through the cell for better energy throughput while minimizing RI effects
  • Low noise performance (<5 µAU)
  • Lamp optimization for the best s/n performance over the lifetime of a Deuterium lamp
  • Flexible sampling rates, from 1 to 80 Hz, for normal and fast LC separations
  • Independent optimization of sampling rates and filter time constants gives you the ability to tune your detector to your separation goals
  • Enhanced thermal wander management reduces baseline wander due to fluctuations caused by ambient conditions
  • Flow cell options to match your separation scale and type
  • Accessible detector components for easy operation and maintenance


  • Wavelength range: 190 to 700 nm
  • Bandwidth: ≤5 nm
  • Wavelength accuracy: +1.0 nm
  • Wavelength repeatability: +0.1 nm
  • Linearity: <5% at 2.5 AU, propylparaben at 257 nm
  • Drift: 1.0 x 10-4 AU/hr. max
  • Thermal drift: 1.0 x 10-4 AU/°C max
