a. If the surface is smooth, a glass mirror is being used.
b. If the surface is rough, or an engraving is detected, a stainless
steel mirror is being used.
To clean either a glass or stainless steel mirror, refer to the instruc -
tions “To clean the mirrors” on page B - 4. To replace a stainless
steel mirror, refer to the instructions for “To replace the stainless
steel mirrors” on page B - 5.
To clean the mirrors
1. Power down the analyzer following the procedure outlined in “To
power down the analyzer” in the Firmware Operator’s Manual.
2. Isolate the analyzer from the sample bypass flow by following the
procedure outlined in “Isolating the Measurement Cell for
Short-term Shutdown” in the SCS Operating Instruction.
3. If possible, purge the system with nitrogen for 10 minutes.
4. Carefully mark the orientation of the mirror assembly on the cell
body.
5. Gently remove the mirror assembly from the cell by removing the six
socket-head cap screws and set on a clean, stable and flat surface
6. Look inside the sample cell at the top mirror using a flashlight to
ensure that there is no contamination on the top mirror.
7. Remove dust and other large particles of debris using a bulb blower
or dry compressed air/nitrogen. Pressurized gas duster products are
not recommended as the propellant may deposit liquid droplets onto
the optic surface.
8. Put on clean acetone-impenetrable gloves.
Do not attempt to replace a glass mirror with a stainless steel
mirror or system calibration may be adversely affected.
Careful marking of the mirror orientation is critical to restoring
system performance upon reassembly after cleaning.
Cleaning of the top mirror is not recommended. Refer to
“Packing” on page B - 18.
