Prior to adding electrolyte to the Ultra Trace sensor, the electrolyte must be
purged with nitrogen (N
2
) to remove most of the dissolved oxygen (O
2
). This
will reduce the time required to remove the dissolved O
2
from the electrolyte
by sparging it with N
2
inside the sensor and hence, shorten the start-up time. To
purge the electrolyte:
1. Prepare the sensor electrolyte by following procedure MP-A56133
included in the Accessory Kit.
2. Open the cap of the electrolyte bottle.
3. Insert the fritted glass tube (P/N T1052) through the opening in the
bottle and bubble O
2
-free N
2
through the electrolyte. The flow rate
of the N
2
should be adjusted so that a large number of small bubbles
can be seen dispersing through the electrolyte.

4. Purge the electrolyte for about one hour.
NOTE: TET/AI recommends that the sensor be purged before adding
electrolyte. This is done by lowering a plastic/Teflon tube (clean
and free of any oil/grease and/or particulates) into the sensor
through the opening on the top of the stainless steel mounting plate
and flushing the sensor with O
2
-free gas. Add electrolyte into the
sensor while flushing the sensor with O
2
-free gas. This will
eliminate the O
2
from the sensor before the addition of prepurged
electrolyte. This procedure will substantially reduce the downtime
associated with clean-up at the first startup of the analyzer.
