OPERATION (CONTINUED)
R EACTIVATING THE C ATALYST C ARTRIDGE
An active catalyst cartridge must be installed to maintain anaerobic conditions. A spare cartridge is
provided with each BACTRON so that cartridges can be swapped out for reactivation. For optimum
performance, reactivate a catalyst cartridge after every 24 hours of use.
To reactivate a cartridge, perform the following:
1. Heat the catalyst cartridge at 200°C overnight prior to installing in the BACTRON.
a. The handle of the cartridge can be removed prior to heating, and reinstalled
afterwards. Use appropriate Personal Protective Equipment (PPE) to prevent
burns.
2. A quality control test should be performed on each cartridge once per month.
Note: A flow of AMG for testing can be obtained by disconnecting the foot pedal gas / vacuum line
from an arm port while the door is closed, and then depressing the Gas pedal.
a. Flow anaerobic mixed gas with hydrogen over a reactivated catalyst cartridge
in a normal aerobic atmosphere. Or place the reactivated catalyst cartridge in
the pass box and run a full auto cycle.
b. The palladium coated pellets inside the catalyst cartridge should grow warm in
the presence of oxygen and hydrogen, indicating that the cartridge is ready for
use.
c. If the cartridge does not heat up when exposed to AMG and oxygen, reheat to
200°C. While the cartridge is still hot, flow AMG over the cartridge in an oxygen
environment. This should help remove any buildup of hydrogen sulfides or
other contaminants that might interfere with the cartridge
’ s effectiveness.
d. Test the room temperature reactivated cartridge again with another flow of
AMG in an aerobic environment.
