6 Maintenance and Troubleshooting
6.2 ION electrode maintenance
148 HORIBA
To fill an electrode with internal solution (inner tube), the
electrode must be disassembled. Use sufficient care
during disassembly.
Items necessary when replacing internal solution are: a
syringe, #330 (gel) reference solution, and the reference
solution specified for the particular electrode.
Filling the electrode: disassembly procedure
1.
Remove the protective tube and tip-type ION
electrode from the combined electrode and put
the rubber cap on the tip-type electrode part.
2.
Remove the rubber stopper from the reference
solution (outer tube) filler port, and take out the
internal solution using a syringe.
3.
Twist the electrode cap by hand and move it
approximately 5 to 10 centimeters toward the
electrode connector.
4.
Remove the internal body of the electrode by
holding the electrode cap by hand, and then
pushing the electrode while it is standing
vertically on a desk or other horizontal surface.
5.
Move the silicon tube from the internal body
downward, to expose the internal solution filler
port (inner tube).
6.
Put the gel-form internal solution (#330) in
through the filler port using a syringe and fill the
