Tips: What are the potential interferences in sodium ISE measurements?

Sodium ion-selective electrode (ISE) measurements may be susceptible to various interferences. Common challenges include ion interference from other cations, such as potassium and lithium, which can cross-react with the electrode and lead to inaccurate sodium readings. pH fluctuations can also impact results, as the sensitivity of the electrode may vary with changes in sample acidity. Additionally, substances like proteins and lipids can foul the electrode membrane, affecting its selectivity and response. Temperature variations may influence electrode performance, requiring temperature compensation for accurate readings. Presence of surfactants or complexing agents in the sample can further complicate measurements. Regular calibration, proper sample preparation, and adherence to recommended procedures can help mitigate these interferences and ensure reliable sodium ISE measurements.
