Mirrors and Herriot Cell Inspection
11.
Inspect far mirror – detector end (left side) for visible signs of contamination. Small levels
contamination can be removed using the cleaning steps outlined in the mirror cleaning procedure
below.
12.
If contamination is visible behind the far side mirror (figure 11) the analyzer has been heavily flooded
and will require cleaning at the factory
13.
Look inside the Herriott cell for signs of moisture.
If there is a small level of contamination on the near end (laser end) mirror, proceed to step 14 to
remove the mirror from the Herriott cell block.
If there is significant contamination on the Herriott cell walls (image above), the analyzer will need to
be sent back to the AMI factory for service.
Re-assemble the analyzer prior to return to AMI.
