Part No.: AD20 Manufacturer: Dionex Qty available: 1 Warranty: 3 month RTB Warranty

This Dionex AD20 Absorbance Detector is a dual-beam, variable wavelength photometer. Full spectral capability is provided by two light sources: a deuterium lamp for ultraviolet detection and a tungsten lamp for visible wavelength operation. The Dionex AD20 features programmable wavelength selection and automatic calibration for precision, reproducibility, and ease-of-use.

Specifications:

  • Light Sources: Deuterium lamp (30 W) for ultraviolet spectrum analysis; tungsten lamp (10 W) for visible spectrum analysis.
  • Wavelength Range: 190 to 800 nm variable;continuous in 1 nm steps.
  • Wavelength Accuracy: ± 1 nm.
  • Bandwidth: 8 nm
  • Absorbance Range: Discrete settings: of 0.001, 0.002, 0.005, 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1.0, and 2.0 AU
  • Autozero Capability: 2 AU
  • Autozero Accuracy: ± 100 uAU
  • Noise: < 10 uAU peak-to-peak at 254 nm, 2-second rise time, flowing deionized water.
  • Drift: < 100 uAU/hour (after warm-up), < 100 uAU/oC (after warm-up)
  • Filter Rise Time: Discrete settings of 0.05, 0.1, 0.2, 0.5, 1.0, 2.0, 5.0, or 10.0 seconds.
  • Analog Output Range: Discrete settings of 0.001, 0.002, 0.005, 0.01, 0.02, 0.05, 0.1, 0.2, 0.5, 1.0, and 2.0 AUFS
  • Cell Body: PEEK.
  • Volume and Optical Path Length: Standard bore cell, used with 4 mm (0.016 in) columns: 9 mL volume, 10mm (0.002 in) optical path length.
  • Maximum Operating Pressure: 1.38 mPa (200 psi) with a heat exchanger; 3.45 mPa (500 psi) without a heat exchanger.
  • Chemical Compatibility: The use of a base stronger than 0.1 M is not recommended, as it will etch the silica windows.

    • The unit is fully operational and in good working order.
