The following procedures need to be performed regularly as part of the standard
maintenance of the Model T102.

This section supersedes the Changing the SO
Manual - PN 07266.
Unlike the T101 which includes an internal scrubber to remove SO
S  SO
before the H conversion takes place, the T102 relies on the SO
2 2
M501-TRS to perform the same function.
The SO scrubber of your M501-TRS utilizes a consumable compound to absorb SO
2
from the sample gas before the TRS is converted to SO
periodically in order for the analyzer to continue measuring TRS accurately and
reliability.
This material is capable of efficiently scrubbing SO
means that if the SO content of the sample gas is typically around 100 ppb, the scrubber
2
will function for approximately 10,000 hours, a little over 13 months. If, however, the
typical ambient SO level of the sample gas is 250 ppb, the scrubber would only last for
2
approximately 4000 hours or about 5 ½ months.
To determine how long the SO
1. Measure the amount of SO
• If your T102 has the multigas measurement options activated, this
can be done by following instructions found in the Setting the Gas
Measurement Mode section in the T101 Manual (PN 07266) and
selecting MEASURE MODE = SO
• Let the analyzer operate for 30 minutes, then note the SO
concentration.
2. Divide 1 000 by the SO
EXAMPLE: If the SO
Operational hours = 1000 ppm/hr ÷ 0.125 ppm
Operational hours = 100 000 ppb/hr ÷ 125 ppb
Operational hours = 8000 hrs
