What is an Ion Selective Electrode?
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.
Which solutions do I need for Ion Selective Electrodes?
METTLER TOLEDO offers all solutions that are needed for successful ion measurements. Find ready-to-use ion calibration standards, ionic strength adjustors and electrolytes.
- Ready to Use Ion Calibration Standards
A high precision solution for ion selective electrodes can be ordered at concentrations of 1000, 100 and 10 mg/L (ppm). In case a lower concentration is needed it can easily be prepared with serial dilution that is explained in the electrode manual.
- Ionic Strength Adjustors for High Repeatability
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 type and amount of ISA can be found in the manual of every ISE.
- Electrolytes for Any Application
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 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.
