| We can eliminate the problem completely making the total ionic strength of all samples and standards the same. We can do this by adding a small volume of a concentrated inert solution to each standard and sample. This is usually 2 ml of ISA (Ionic Strength Adjuster) to 50 ml of standard and sample. | We can eliminate the problem completely making the total ionic strength of all samples and standards the same.

| Ion selective electrode measurements are also susceptible to interfering ions that will falsify a correct reading. It might be required to eliminate those interfering ions when their level is too high. This is specific for each type of ISE, see their manuals. | Ion selective electrode measurements are also susceptible to interfering ions that will falsify a correct reading.
