The 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.
| Specification | |
| Optical System | Dual-beam, fiber-optic beam splitter and concave holographic diffraction grating |
| 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 |

| 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, 10 mm (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. |
