9.7.1 System settings - UV
The following table describes the UV related system settings available for ÄKTA avant.
Description Instruction name
Enables or disables the alarm for the UV 1 signal from
UV monitor U9-M. When enabled, it sets the alarm limits
for the UV 1 signal. When the signal falls outside the set
limits, an alarm is issued and the method will be paused.
Note:
It is not possible to set an alarm signal for the UV 2 or
UV 3 signals from UV monitor U9-M.
Alarm UV1
Enables or disables the alarm for the UV signal from U9-
L, 2nd. When enabled, it sets the alarm limits for the UV
signal from UV monitor U9-L, 2nd. When the signal falls
outside the set limits, an alarm will be triggered and the
method will be paused. Alarm UV 2nd
Sets the wavelengths for UV monitor U9-M. The corre-
sponding curves in the chromatogram are marked with
the set wavelengths.
Note:
•
The instruction is available when UV monitor U9-M
(variable) is selected in the component list. For best
performance, do not use more wavelengths than
necessary for the application.
•
At low wavelengths, the eluent can have significant
absorbance of its own.
Wavelength
Filters the noise in the UV signal from U9-M or U9-L
(depending on the configuration). A column-specific
averaging time is set automatically when a column is
defined in a method run and Averaging time is set as
a variable. Noise reduction UV
Filters the noise in the UV signal from U9-L, 2nd. A col-
umn-specific averaging time is set automatically when
a column is defined in a method run and Averaging
time is set as a variable. Noise reduction UV 2nd
