18.
Remove and discard o-rings from removed endcaps.
19.
Using the AMI supplied optical wipes and 99% pure isopropyl alcohol, apply a few drops onto the
wipe and then lightly rub one of the mirrors surfaces. Use light pressure only and small circular
motion.
20.
Repeat this process with a new wipe and additional alcohol drops until all contamination is removed.
Carefully blow dry with the can of dry nitrogen.
21.
Make sure the mirrors surface is free of any streaks. If not repeat steps 18 and 19.
22.
After both mirrors are clean, pre-lubricated o-rings and carefully into endcaps.
23.
Wet the suave with alcohol and carefully run it through the full length of the Herriott Cell block until
clean. Then blow dry with the can of Nitrogen.
Mirror Cleaning Process
The Herriot cell mirrors are precision optics. Any damage to the surface of the mirrors can result in
degradation of analyzer performance. Please use the following steps for cleaning the mirror surfaces.
WARNING
24.
Begin the reassemble by carefully reinstalling the near side mirror – laser end cap. Holding the strain
relief, make sure the dowel pins are aligned and slip the near end cap into place.
25.
Make sure the fiber optic loop is still intact with its appoximately. 1” (25mm) radius and secure with
the 6-32 nut (figure 17).
26.
Place the 4 socket head screws in place and begin tightening in a star pattern. When assembling
near mirror endcap.
Analyzer Re-assembly
When re-installing the Ends Caps, be careful not to hit the mirrors on the dowel pins. This can cause
scratches on the mirror and any damage to the surface of the mirrors can result in degradation of
analyzer performance.
