3.2 Monitor principle
A Xenon flash lamp gives a high intensity, continuous spectrum of light. The lamp is on
only during the chromatographic run, ensuring that its long lifetime is used in the most
efficient way.
The light enters an interference filter based monochromator which includes a collimating
system and a filter unit with a fixed specific wavelength. It is possible to select wavelength
between 200-700 nm by changing filter unit.
