Turning On the Lamps

Thermo Scientific
As lamps age, they emit less light, which results in increased baseline noise. If the noise level
on your detector signal is unacceptable, and cleaning the LightPipe flowcell does not help, use
the diagnostic features of the software to determine the cause of the problem. If light output
becomes too low and adjusting the attenuators as described in
Throughput with the Xcalibur Data System"
The detector keeps track of the number of hours each lamp has been operating. The
deuterium lamp has a lifetime of approximately 2000 hours and the tungsten lamp has a
lifetime of approximately 2500 hours. Lamp lifetime varies depending on the application (see
"Lamp Lifetime and Detector Noise"
