It is recommended that the lamp be replaced
if it will not ignite, the noise or drift exceeds
specifications, or if the lamp energy is below
50% of original intensity, as recorded during
the initial installation.
4.0 Installation Information
CTS
’s parts are designed to be compatible
and interchangeable with the OEM parts.
1. Power down the PDA detector.
2. Remove the power cord.
3. Wait 15 minutes for the detector
lamp to cool before handling the
lamp.
4. Remove the optics cover to access
the lamp.
5. Disconnect the lamp power
connector.
6. Unscrew the two mounting screws.
7. Grip the metal base and pull the
lamp out.
8. Remove the mounting screws from
the old lamp.
9. Carefully unpack and hold the
replacement lamp by its base only.
10. Orient the lamp so the two holes in
the base align with the mounting pins
and screws in the optics bench.
11. Insert the lamp and secure it with the
two mounting screws.
12. Reconnect the lamp power
connector.
13. Close detector housing.
14. Reconnect the power cord and power
up PDA detector.
15. Record initial lamp intensity in the
instrument log.
5.0 Operating
Recommendations
5.1 Lamp Intensity
It is known within the industry that
deuterium lamps exhibit reduced
intensity as they age during their normal
service life. It is recommended that a
diagnostic test, showing PDA intensity
levels, be run on the lamp at
installation, then regularly during the
lamp
’s service life. It is also
recommended that the lamp be replaced
at 50% of original intensity.
5.2 Installation and
Transportation
The lamp is sensitive to physical shock
such as being dropped. It is
recommended that you avoid shock
when installing or transporting the
lamp. If it is suspected that a lamp has
been subjected to excessive shock, it is
recommended that a diagnostic
PDA Intensity Test is run to verify that
intensity is acceptable. An acceptable
PDA Intensity Test will not, however,
guarantee that no damage occurred.
5.3 Fingerprints
Fingerprints on the glass envelope
affect the lamp
’s performance. It is
highly recommended that the lamp
’s
envelope not be touched unless wearing
gloves. If there is any chance that there
are fingerprints on the lamp
’s envelope,
wipe the envelope with methanol using
a lint-free tissue and allow to dry prior
to installation.
5.4 Flow Cells
It is important to clean the flow cell
regularly. If the flow cell is not clean,
the amount of light passing through the
flow cell may be insufficient and could
affect the light intensity. If after
replacing a lamp the detector performs
poorly; it is recommended that you
check to make sure that the flow cell is
clean and leak free.
