Replacing the Deuterium Lamp
1. Stop the PeakNet 6 or Chromeleon server.
2. Turn off the PDA-100 power switch.
3. Grasp the detector front panel by the sides and pull straight off to remove.
4. Remove the tubing bracket from the lamp cover (see Figure 5-1).
5. Remove the flow cell inlet tubing from the tubing guide in the lamp cover (see
6. Remove the flow cell cover from the inside front panel (see Figure 5-1).
7. Move the flow cell tubing out of the way. Remove the four screws holding the
lamp cover in place, and then remove the cover and set it aside.
8. Squeeze the clip on the UV lamp connector and disconnect it from the 6-pin
bulkhead connector on the side wall (see Figure 5-3).
9. Loosen the three screws in the deuterium lamp flange (see Figure 5-3) and
pull the lamp out of the optical bench.
NOTE The screws are captive in the lamp base and do not need
to be removed.
10. Inspect the new deuterium lamp (P/N 939016T) for fingerprints and dust. If
necessary, clean the lamp with isopropyl alcohol (IPA).
11. Line up the flange of the new lamp with the two locating pins and three
threaded holes in the optical bench (see Figure 5-3). When the flange is
aligned, gently push the lamp into the optical bench.
The lamp housing and base may be hot to the touch, especially after
the lamp has been in operation for a long time. Wait until the lamp has
cooled down before continuing.
La lampe et la base de la lampe peuvent être chaudes au toucher,
particulièrement après que la lampe a été allumée pendant longtemps.
Attendez que la lampe ait refroidi avant de continuer.
Das Lampengehäuse und die Lampenbefestigung können sehr heiß
werden, besonders wenn die Lampe längere Zeit in Betrieb war.
Warten Sie, bis die Lampe abgekühlt ist, bevor Sie diese berühren.
