    In general, if any optical component other than the cell assembly, laser module, and the detector are deemed unserviceable, the analyzer must be repaired by Emerson personnel. The repair, replacement, and alignment of the optical components requires the use of specialized optical test/calibration equipment and procedures to ensure the correct operation of the unit.
