2. Thread the two screws you removed into the two threaded holes in
the backside of the mirror. Use a flat blade screw driver, inserted
under the screw head and carefully pry up on each one to remove
mirror from optics block (mirror removal tool S7000150 can also be
used).
3. Inspect mirror surface. If dirty,
blow off with clean dry
compressed air. If it still does not
appear clean, wipe gently with a
soft lens cleaning tissue dipped
in isopropyl alcohol.
4. Inspect O-ring on mirror for
cracks or abrasions and replace
if necessary. See service kit

item 1.
5. If the O-ring is dry, apply a small
amount of vacuum grease to the
outer surface.
6. Inspect the sample inlet near the
detector and clean if necessary.
