9.1.1.2. Checking the Function of the SO
2
Scrubber
To check to see if your SO
2
scrubber is operating properly perform the following test:
1. Set the analyzer for TRS gas measurement mode (see Setting the Gas
Measurement Mode section in the T101 Manual - PN 07266).
2. Set the reporting range to range of 1000 PPB (see Sections 6.7.4, 6.7.5
and 6.7.6 of the T101 Manual - PN 07266).
3. Introduce a gas mixture into the sample gas stream that includes 500
PPB of SO
2
.
An increase of more than 10 PPB in the TRS reading is an indication that the efficiency
of the scrubber is decreasing to the point that the absorbing material should be replaced.
9.1.1.3. Changing the SO
2
Scrubber Material
1. Input zero air for 5 minutes
2.
Turn off the M501-TRS
3.
Locates the SO2 scrubber cartridge on the right side of the converter:
It looks like a big white cylinder (See Figure 3-2 of this addendum).
4.
Undo the two 1/4 inch fittings on the top of the scrubber
5.
Remove the two screws holding the scrubber to the instrument chassis
and remove the scrubber
6.
Take the two Teflon fittings off the instrument.
7.
Empty the SO
2
scrubbing material into a hazmat bin.
8.
Fill each side of the scrubber with new SO2 scrubber material until it is
½ inch from the bottom of the thread lines (about 1 inch from the top of
the scrubber), do not fill it too high or the fitting will compact the
material, causing a restriction in the gas flow.
9.
Remove the Teflon tape from both of the removed fittings, and wrap
them with new Teflon tape.
10.
Install both fittings back onto the scrubber.
11.
Put the scrubber back into the analyzer and replace the two screws on
the bottom.
12. Screw the two 1/4” fittings back onto the top of the scrubber (either
fitting can fit the inlet or the outlet). Return analyzer to normal
operation
