Electrode preparation
1. Remove the protective cap encasing the chloride
probe's electrode.
CAUTION: Do not touch the PVC membrane at the
end of the probe with your fingers.
2. Rinse the electrode with deionized water and blot
dry. Be sure not to rub as this will harm the sensor.
3. Soak the electrode in deionized water for 10 minutes,
then in a diluted chloride standard solution (0.0001 M
or 1 ppm) for two hours until ready for use.
4. For preparing the 1 ppm standard solution, mix one
drop of the 1000 ppm standard solution with 20
drops of ISA and add deionized water up to a total of
40 ml solution (assuming one drop equals 0.04 ml). It
is also possible to use a micropipette if available.
