Replacing the Electrolyte in the Ultra Trace Sensor

CAUTION:
The electrolyte in the Ultra Trace sensor must be replaced when the background
signal is unusually high and the analyzer is unable to adjust the zero. A high
background level is the result of dissolved oxygen in the solution, which occurs
when the Ultra Trace sensor is exposed to high oxygen concentrations for long
periods of time. The dissolved oxygen can be removed by replacing the
electrolyte.
To replace the electrolyte:
1. Turn the analyzer to Analyze mode.
2. Remove the anode terminal wire (black wire). The analyzer will
display 0.0.
3. Remove the anode from the stainless steel plate on top of the Ultra
Trace sensor body. Store it in the holder in which it was shipped,
after wetting the holder with a little electrolyte.
4. Use the 50 cc syringe (P/N B51752) provided to remove the electro-
lyte from the Ultra Trace sensor.
5. Add the pre-purged sensor electrolyte (see Chapter 3 and Quick
Reference: Start Up) to the Ultra Trace sensor until the electrolyte
level is just below the green marker on the Ultra Trace sensor body.
6. Rinse the anode with fresh electrolyte. Then reinsert it into the
anode port, and tighten it onto the stainless steel plate.
7. Reconnect the anode terminal wire to the sensor's anode terminal.
8. The analyzer will display the signal which will vary depending on the
amount of dissolved oxygen in the electrolyte. The signal output will
gradually decrease as the dissolved oxygen is removed by sparging
the electrolyte. The down-time to PPB range should be about 10–24
hours.
Protective equipment including but not limited to gloves,
safety glasses, face shield and rubber apron must be worn
while handling electrolyte. The safety of the people in the
vicinity of the area in which the electrolyte is being
handled must be given similar consideration. Please refer
to Material Safety Data Sheets to learn about potential
hazards and corrective action in case of accident.
