4.3 Control the UV Lamp
The internal detector uses an ultraviolet (UV) lamp and, if using the UV-VIS detector, a tungsten lamp in
its detection process. The UV lamp must be warmed up in order for the signal to be accurate and stable.
NOTE
The UV lamp should be turned on 7.5 minutes before starting a purification
so the UV lamp can reach operating temperature.
The lamp(s) is/are automatically turned on when:
• The Isolera system is switched on.
• The user enters the Chemistry mode (i.e. press the Chemistry button in the main menu).
• The user starts a run (i.e. press the button in the
Run Parameters dialog). However, before
starting the run, the software waits (approximately 7.5 minutes) for the UV lamp to warm up.
You can also turn on the detector lamp(s) manually by pressing Turn Lamp On in the right-hand
panel. By doing this ahead of time, you can avoid the delay that is required if the software turns the
lamp(s) on at the start of a run.
To prolong lamp life, the lamp(s) is/are turned off automatically if the system is idle (no purification
is started and no user interaction is detected) for approximately two hours.
Bypass the Automatic UV Lamp Warm-up Period
You can bypass the automatic UV lamp warm-up period by pressing Skip Warm Up in the right-
hand panel. However, if the UV lamp has not reached operating temperature, purification results
may not be optimal.
