1.9.1 Optical description
The laser modules are located in the core of the analyzer. Each laser module produces a
separate light beam, and these beams are combined linearly as the modules are aligned in
the system. The combined beams are closely coupled, parallel, and coaxial about a virtual
line. The laser light beams pass through a baseplate onto an optical steering assembly,
which directs the laser beam through the sample cell.
The sample cell contains a set of mirrors to create a path through the sample gas that is
between 2 m and 5 m through multiple reflections along the length of the cell. The laser
beams exit the cell at the opposite end from where they entered and are directed using a
second optical block to a receiver.
By measuring and analyzing the light detected by the receiver unit, it is possible to
accurately determine the concentrations of the target molecules within the gas sample
cell.
1.10 Unpacking the analyzer
This procedure may require a minimum of two people to safely remove the equipment
from the shipping container.
WARNING!
HEAVY ITEM
Handle the analyzer with caution during unpacking, installing, maintaining, and transporting

WARNING!
TRANSPORTATION HAZARD
Use safety-approved lifting equipment. You must ensure safe lifting procedures for the weight
and mass of the equipment are followed.
Failure to use proper lifting procedures may cause injury to personnel or damage the analyzer.
Procedure
1. Visually inspect the exterior of the analyzer for signs of damage, corrosion, gas
leaks, or signs of previously overheating.
2. Report anything found to the maintenance organization.
3. One person carefully guides and assists the other person lifting the equipment from
the container.
4. If necessary, use safety approved and tested lifting equipment to remove the
analyzer from the shipping container.
