Function of UV monitor U9-L
The UV monitor U9-L measures the UV absorbance at the fixed wavelength of 280 nm.
It is not possible to vary the wavelength, or turn on or off the U9-L monitor. This is therefore not shown
in the Phase Properties pane in Method Editor.
Location and illustration of UV monitor U9-L
The illustration below shows the recommended location of UV monitor U9-L, together with a detailed
view of the monitor and detector. The UV monitor U9-L requires that the Multi-module panel is installed,
see Example of a typical configuration of the wet side, on page 16. The UV monitor can also be installed
in an Extension box, see Extension box, on page 86.

Using two UV monitors
It is possible to use two UV monitors in ÄKTA pure, in two combinations. The configuration is defined
by the module's Node ID.
