6.5.2 Guidelines for Use of the Lamps
The table shows which lamp is recommended if at least one of your
detection wavelength is within the range indicated in the left column.
The values apply to single-channel and 3D data field measurements.
At least one detection wavelength Recommended lamp
≤ 345 nm UV lamp (deuterium lamp) is required.
Between
346 and 670 nm UV lamp (deuterium lamp) or VIS lamp
(tungsten lamp), if available. If both lamps are
available, it is recommended to turn on both.
> 670 nm VIS lamp (tungsten lamp) is recommended. If
no VIS lamp (tungsten lamp) is available, use
the UV lamp (deuterium lamp).
6.5.2.1 Turning on the Lamps
You can turn on both lamps using the UV and VIS buttons on the keypad
of the detector or using Chromeleon (see Important Operating
Parameters ( } page 95) ).
TIP
To ignite the lamps, the lamp house cover must be installed. If you
remove the lamp house cover while either of the lamps, or both lamps
are turned on, the lamps are turned off automatically and cannot be
reignited as long as the lamp house cover is not installed.
The lamps require some time to warm up for optimal performance
before analysis. Before you start analysis, allow the lamp(s) to warm up
and stabilize for
at least one hour until the working temperature is
reached. Also, allow the lamp(s) and the optics to warm up after each
lamp configuration change.
TIP
When the UV lamp was turned off, a cooling-off period of 5 minutes is
required before the lamp can ignite again. The detector monitors the
cooling-down period. If the lamp is turned on again after less than
5 minutes, a message appears in the Chromeleon Audit Trail followed by
a countdown until the lamp is ignited.
