10. Air dry the tube.
11. Check the cleanliness by looking down the bore of the tube.
•
It should be free from dirt and lint.
12. Inspect the o-rings that seal the ends of the optical tube (these o-rings may stay
seated in the manifolds when the tube is removed.)
•
If there is any noticeable damage to these o-rings, they should be replaced.
13. Re-assemble the tube into the lamp housing and return the top cover of the optical
bench.
14. Prior to tightening the retainer screws, gently push the tube all the way toward the
front of the optical bench when it is reassembled; this will ensure that the tube is
assembled with the forward end against the stop inside the detector manifold.
15. Return the cover to the analyzer and power up the analyzer.
16. Perform an
AUTO LEAK CHECK
on the instrument.
