System settings - UV

The table below describes the UV related system settings available for ÄKTA pure.

Description

Instruction name

Alarm UV enables or disables the alarm for the UV signal. When
enabled, it sets the alarm limits for the UV signal from UV monitor
U9-L. When the UV signal falls outside the set limits, an alarm will
be triggered and the method will be paused.

Alarm UV

Alarm UV 1 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

Alarm UV 2nd 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

Wavelength sets the wavelengths for UV monitor U9-M. The cor-
responding 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

Noise reduction UV filters the noise in the UV signal from U9-M
or U9-L (depending on the configuration). A column-specific aver-
aging time is set automatically when a column is defined in a
method run and Averaging time is set as a variable.

Noise reduction UV

Noise reduction UV 2nd filters the noise in the UV signal from U9-
L, 2nd. 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 2nd
