Limas11: Aluminum Sample Cell Cleaning, continued
Step Action
Sample Cell Installation:
10 Place the sample cell in its housing. The index pin should be on the
side of the sample cell that is toward the beam splitter. Turn the
sample cell in its housing until the index pin engages in the hole in the
housing.
11 Install the 2 mounting brackets 2 and secure them with the 4 screws 1.
12 Install the sample gas tubing or pipes on the sample cell ports and on
the module’s rear wall.
13 Check the integrity of the analyzer module gas paths (see page 9-2).
Restarting the analyzer module:
Close the system housing. 14
Light penetration during operation leads to erroneous measure-
ment values and measurement range overflows (“Intensity”
status message).
15 Turn on the gas analyzer power supply.
16 Wait for the warm-up phase to end. Start the sample gas supply.
17 Check linearity.

Connection
An aluminum sample cell with center connection is built-in in the Limas11UV ana-
lyzer module with Class 2 NO measurement ranges. In this version, the sample
gas inlet is in the center and the sample gas outlets are at the ends of the sample
cell. This has to be observed when re-installing the sample cell after cleaning.
