g. Inspect the interior of the Cell Body for foreign material. If neces-
sary, use a cotton swab to clean the Cell Body.
If a more thorough cleaning is required, use only cleaning materi-
als that are suitable for use with the sample species and the Cell.
Clean the fittings using the same method as the Cell Body.
For example:
If suitable for the species, an acceptable material is Chem-Thane
– or a nonabrasive detergent and water solution. The Cell Body
can then be rinsed with reagent-grade acetone (if suitable), fol-
lowed by a rinse with pharmaceutical-grade distilled water.
h. Allow all components to dry thoroughly before reassembling. Dry,
oil-free instrument air can be used to remove any remaining mois-
ture from the passages in the Cell Body and fittings.
6. Replacing parts/reassembling the Measuring Cell:
a. Insert a new o-ring in the o-ring groove on the flat surface of the
Reflector Block.
With the Cell held vertically so that the Reflector Block end of the
Cell is up, install a new o-ring by using your thumbs to push it
into the o-ring groove until it is completely seated in the groove.
While holding the edge of the Window, carefully place it in the
Cell.
Orient the Reflector Block correctly, and place it on the Cell.
Ensure the Cell Window does not slide out of position when the
Reflector Block is placed against the Cell.
It is critical to reassemble the Reflector Block in the exact orientation
as it was assembled at the factory.
Secure the Reflector Block to the Cell using three M4 x 20 mm
screws. Tighten the screws evenly.
b. With the Cell held vertically so that the Reflector Block end is
down, install a new o-ring by using your thumbs to push it into
the o-ring groove until it is completely seated in the groove.
While holding the edge of the Window, carefully place it in the
Cell, on top of the o-ring. Install a second, new o-ring on top of the
Window.
If an Optical Bench/Cell Insulator is used, properly align it and
secure it to the Cell using the three M4 x 12 mm screws.
