7.3 Maintenance of analyzer unit

7.3.1 Cleaning method for sample cell (pipe cell)

This section is strictly factory adjusted.  Handle it with utmost attention.

If it is absolutely required, contact us.

q

Turn off the power switch, stop the
sample gas, and allow the zero gas to
flow for several minutes to purge the
cell interior.

Loosen the setscrew (2 pieces) from
the top cover and remove it.

w

Remove the internal gas inlet tube.

e

 Loosen both right and left screws for
cell holding plate.

•

 Remove the sample cell only.

r

Turn to the left the sample cell window
and remove it from the sample cell (see
Fig. 7-1).

t

For cleaning the window and cell
inside surface, first eliminate coarse
dust by soft brush or the like and then
wipe them by soft rag.

The window is easy to get scratched.
Pay utmost attention so as not to
damage it.

y

After the end of sample cell cleaning,
mount the cell in place and proceed to
running.
After cleaning sample cell, be sure to
perform optical zero adjustment (see
Item 7.3.3) and moisture interference
compensation adjustment (see Item
7.3.4).

A slightly corroded infrared transmission window or sample cell can be remedied by gently rubbing
with chromium oxide powder on cleaning cloth but an excessively corroded one must be replaced.
When cleaning, do not exert an excessive stress.
