Controlling Hydrogen Ion Interference During Sodium
Sample circumstances may have an impact on sodium ion selective electrodes, particularly when the concentration of hydrogen ions varies considerably.
To increase the stability of measurements:
1.Keep the sample's pH at the proper level.
2.Make use of sodium calibration standards.
3.When necessary, apply an alkaline reagent.
4.Observe the suggested methods for sample preparation.
Alkaline reagents like diisopropylamine can be employed for some samples to improve sodium ion response stability and lessen hydrogen ion interference.
