High-accuracy ion calibration standards for calibration can be ordered at concentrations of 10, 100, and 1000 mg/L (ppm). If a lower concentration is needed, it can easily be prepared with a serial dilution.
In all analytical procedures using an ISE, the correct amount of ISA (Ionic Strength Adjustor) must be added to all samples and standards prior to measurement or calibration. This solution ensures that samples and standards have similar and constant ionic strength.
It is important to fill the reference electrode of every ISE with the recommended electrolyte solution. The correct electrolyte will minimize junction potentials and provide optimum temperature and response time. The electrolyte must be refilled or replaced regularly to maintain good electrode performance.
For maximum traceability, an individual certificate of analysis exists for every batch of ISE or ISA solution. Contact pH-CSC in order to get the solution certificate and print it for documentation purposes.
To remain compliant with regulations is important. Every SDS (Safety Data Sheet) and label contains information according to the GHS (Global Harmonized System) in local languages.

Measuring with ion-selective electrodes (ISE) is the easiest and most affordable way to determine ion concentration. However, ISEs require careful handling and the use of the correct solution for ion-selective electrodes. METTLER TOLEDO offers all solutions that are needed for successful ion measurements:
A ready-to-use ion calibration standard is a high-precision solution for ion-selective electrodes. It can be ordered at 1000, 100 and 10 mg/L (ppm) concentrations. If a lower concentration is needed, it can easily be prepared with serial dilution, as explained in the electrode manual.
In all analytical procedures using an ISE, the correct amount of ISA (Ionic Strength Adjustor) must be added to all samples and standards prior to measurement or calibration. This solution ensures that samples and standards have similar and constant ionic strength. Instructions for the type and amount of ISA can be found in the manual of every ISE.
It is essential to fill the reference electrode of every ISE with the recommended electrolyte solution. The correct electrolyte will minimize junction potentials and provide optimum temperature and time response. The electrolyte must be refilled or replaced regularly in order to achieve good electrode performance. For more information, please refer to the electrode manual.
