If your system has been configured with a stainless steel mirror in the 0.1 m
or 0.8 m measurement cell, use the following instructions for replacing the
mirror.
1. Power down the analyzer following the procedure outlined in the
section called “Powering Down the Analyzer” in the Firmware
Manual.
2. Isolate the analyzer from the sample bypass flow by shutting off the
appropriate valve(s) and/or pressure regulator.
3. If possible, purge the measurement cell with nitrogen for 10
minutes.
4. Gently remove the mirror assembly from the cell by removing the
socket-head cap screws and set on a clean, stable and flat surface.
5. Confirm need to replace mirror due to contamination. If yes, set
mirror aside.
6. Put on clean acetone-impenetrable gloves.
If stainless steel mirrors are replacing another version of mirror in
the field, such as glass, the analyzer may need to be returned to
the factory for re-calibration to ensure optimal cell function.
Contact Service for factory return (refer to “Service Contact” on
page B-31).
All valves, regulators, switches, etc. should be operated in
accordance with site lock-out/tag-out procedures.
Process samples may contain hazardous material in potentially
flammable and/or toxic concentrations. Personnel should have a
thorough knowledge and understanding of the physical properties
and safety precautions for the sample contents before operating
the SCS.
The sample cell assembly contains a low-power, 10 mW MAX, CW
Class 3b invisible laser with a wavelength between 750 to
3000 nm. Never open the sample cell flanges or the optical
assembly unless the power is turned off.
Always handle the optical assembly by the edge of the mount.
Never touch the optical surfaces of the mirror.
