Electrode Maintenance
• Rinse the ion selective electrode thoroughly with distilled water
after use, wipe clean with a lint-free tissue, then replace
protective cap and store the electrode in a dry, cool and well-
ventilated area.
• Never scratch the ion sensitive membrane on the bottom of the
electrode.
• If the electrode response becomes sluggish, soak the electrode
in 100 ppm standard solution for at least 1 hour.
Appendix
Preparation of Ion Standard Solution (1000 ppm)
1. Half fill a 1 liter volumetric flask with distilled water and add the
analytical grade reagent according to the instructions in table
below.
2. Swirl the volumetric flask gently to dissolve the reagent and fill
to the mark with distilled water.
3. Cap and upend the volumetric flask several times to mix the
solution.
