e. Using a clean paper towel, clean the mirror surface of the plug. If necessary, use a
solvent as methylene chloride or methanol to remove deposits and a metal polishing
paste to restore it to the previous reflectivity.
f. Insert the mirror plug in the detector body and fix it with the relevant Allen screws.
See Figure 309.
Note Before reinserting the plug, inspect the graphite seal inside the plug's
housing. If the seal is damaged and could not ensure tightness, remove it and
replace with a new one.
