7.2 Lamp

The lamp must be replaced only by Thermo Fisher Scientific Service for Dionex HPLC
Products. Never try to exchange the lamp or open the enclosure yourself.
You can monitor the lamp age. This function can help to decide when a lamp is due to be
replaced.
Lamp Age
Tip: You can extend the lifetime of the Xenon lamp to about four times the lifetime
compared to Standard mode by switching to LongLife mode. However, note
that sensitivity is roughly halved.
On the basis of the number of lamp flashes, Chromeleon calculates a value that indicates how
many hours the lamp was operated. The value is based on the assumption that the lamp was
operated in Standard mode. For the calculation of the expected lamp lifetime, one operating
hour is weighted depending on the selected lamp mode.
Mode 1 operating hour is counted as ...
LongLife 0.25 hours
Standard 1 hour
HighPower 3 hours
Example: If the lamp age in Chromeleon indicates 2000 hours, this means that the lamp
has reached about the half of its lifetime. Thus, if the lamp is operated in LongLife mode,
it is expected to operate for another 8000 hours.
1. Open the Commands dialog box for the detector.
2. Select the EffectiveLampAge parameter. If the value exceeds 4000 hours, the lamp
should be replaced by Thermo Fisher Scientific Service for Dionex HPLC Products.
