11-3 Electrode Components
①
Membrane
②
Dissolved oxygen electrode(Cable length Approx. 5m)
③
Internal uid inlet
④
Membrane(Replacement)
⑤
Internal uid 30mL(0.5M NaOH)
⑥
Dropping pipet 1mL(Internal uid for injection)
11-4 How to Inject Solution
•
Separate the membrane from the electrode.
•
Fill the membrane with 1mL of 0.5M NaOH using a dropping pipette.
•
Assemble the membrane onto the electrode.
•
Be sure not to tighten the membrane rmly but let it be a little loose so that the
solution may leak.
•
Loosen the solution opening using a at-head driver.
•
Inject the solution through the opening.
•
Do the injection until the solution oozes between the sensor and the membrane.
