Online ISE Analyser
Configure online ion-selective electrode measurement with controlled sample conditions, ionic-strength adjustment, calibration and automatic result reporting.
Select an electrode around the ion and sample
An ion-selective electrode develops an electrical response related to the activity of a target ion. pH, ionic strength, temperature, concentration range and interfering ions affect method selection.
AccuSeries can automate sample capture, buffer addition and measurement. PMA agrees the reporting form, conditioning, calibration standards and verification procedure.
Specify the complete method
01
Define the target ion
Specify the chemical form, reporting basis and expected range.
02
Control sample conditions
Review pH, ionic strength, temperature and interfering ions before choosing the buffer sequence.
03
Plan calibration and checks
Agree standards, known addition where applicable, electrode care and laboratory comparison.
Continue through the AccuSeries method network
Connect analytical methods, parameter requirements and application duties while keeping sample and verification context.
Fluoride
Compare fluoride ISE and SPADNS colorimetry against range and matrix.
Ammonia and ammonium
Define which chemical form and reporting basis is required.
Sodium
Review range, ionic conditions and sample handling.
Nitrate
Assess range, sample matrix and interferences.
Method boundaries
Final method, range, materials and performance depend on the real sample and configured analytical sequence. PMA confirms these details before selection.
Information needed for an ISE application
The electrode, buffer sequence and calibration strategy form one method.
- Target ion and required reporting basis.
- Normal, low and upset range.
- Sample pH, ionic strength and temperature.
- Interfering ions and treatment chemicals.
- Reference method, standards and verification frequency.
- Electrode maintenance, cleaning and replacement plan.
Discuss your ISE application with PMA
Share the target ion, range, sample composition and reference method. PMA can review electrode suitability, conditioning, calibration and support.
