Source Lamp Replacement
The typical life span of the source lamps is approximately 9–12 months of
continuous operation. However, a source lamp can exhibit signs of degra-
dation after 5–6 months.
When Do Source Lamps Need to be Replaced?
Possible signs of degradation or indications of Source Lamp failures are:
• Unstable lamp voltage (check voltage levels on Optical Bench Data
tab.
• Unstable analyzer output under Zero gas conditions (“w: Excessive
zero drift” alarm is displayed on Status tab).
• The “w: ALC out of range” (or automatic “w: PMT signal out of
range”) alarms are displayed on the Status tab.
