Selector™ Diffuse Reflectance Accessory
31
7. Care and Maintenance
When the Selector™ accessory is not in use it can be carefully stored
away in its own carry case. This will prevent the potential for any dust
or marks accumulating on the mirrors and optical components of the
optical unit (
1
) which would impair the throughput performance of the
accessory.
If for any reason finger marks or dirt are found on a mirror surface, the
contaminant may be removed by gently and carefully cleaning using an
appropriate solvent moistened soft lens tissue
to dab
at the surface of
the mirror. (Water, methanol and acetone are suitable solvents to use
for cleaning.)
Do not
try rubbing or using an abrading action with the
lens tissue against the surface of the mirror as this introduces a risk of
creating scratches and indelible marks on the mirror surface which will
severely impair the throughput performance of the Selector™
accessory. If you are in any doubt about the condition of a mirror
surface and how this can be cleaned safely, please seek advice from
Specac or your local Specac representative.
For the sample cups (
19
,
20
and
23
) cleaning, for any sample, but
particularly if a salt sample such as KBr or NaCl has been used,
Specac recommends that the cups are washed first with cold water to
dissolve any residual salt content and are then rinsed with methanol to
remove any potential organic residues. Any moisture remaining after
this rinsing is removed by finally drying the cup with a tissue.
The diabraze pads (
21
) are considered to be consumable items and so
after sampling, the diabraze pad (
21
) is removed from its mount holder
(
22
) and can be discarded. The surface of the mount holder (
22
) can
be cleaned using methanol and a tissue to wipe away any residual
adhesive to prepare the mount holder in acceptance of a new diabraze
pad (
21
). Replacement diabraze pads are available as a packet of 100
pads under P/N GS19919.
