Wavelength Calibration

Dionex UV detectors fitted with a Holmium Oxide Filter perform a wavelength calibration after each Lamp = on command (see Lamp) or Connect command.

Dionex AD25, PDA, PDA-100, and PDA-3000 detectors perform a wavelength calibration at power-up. New wavelengths are assigned to each pixel, based on the emission spectrum from the deuterium lamp.

With defined absorption maxima, wavelength calibration ensures that the data delivered by the detector corresponds to the expected wavelength values.
