Define the target ion
Specify its chemical form, reporting basis, units and required concentration range.
Ion-selective electrode measurement with controlled sample conditions and PMA support.
An ion-selective electrode develops an electrical response related to the activity of a target ion. AccuSeries can automate sample capture, conditioning, measurement and result reporting for an appropriate electrode method.
Sample pH, ionic strength, temperature and interfering ions affect the measurement. PMA reviews the target chemical form, buffer sequence, calibration standards and reference procedure together.

Specify its chemical form, reporting basis, units and required concentration range.
Review pH, ionic strength, temperature and interfering ions before selecting conditioning.
Agree standards, known addition where applicable, cleaning and reference comparisons.
Compare fluoride ISE with a suitable colorimetric method for the sample range and matrix.
Define the chemical form and reporting basis before selecting the electrode configuration.
Review the ion, measurement range, interfering constituents and sample handling.
The selected chemistry, range and preparation must represent the actual sample. Online process information supports the agreed operating decision and verification plan.
Share the analyte and chemical form, reporting units, normal and upset range, sample composition, colour and solids, temperature, transport conditions, reference method, required result frequency, number of streams and outputs. Include maintenance access, reagent replenishment and waste handling.
PMA has supported process measurement and analysis since 1971. We connect your analytical objective with the sample, instrument, installation and operating team.
Talk to us about application review, commissioning, training, service and ongoing reagent supply.

Search PMA’s parameter, product and application finder using your analyte, method or operating duty.
Its response relates to the activity of the target ion under the method’s sample conditions. Conditioning and calibration connect that response with the required reported result.
No. Electrode choice, range, sample conditions and interferences are specific to the ion and analytical method.
pH, ionic strength and temperature can affect electrode response. The buffer sequence, calibration and maintenance plan form part of the complete method.
Compare the platform, industries, technical overview and public application notes.
Automate a defined colour-development reaction for nutrients, selected metals and other compatible water and process chemistries.
Measure a defined titratable quantity using controlled reagent addition and optical or potentiometric endpoint detection.
Review whether one platform can serve several sample points and analytical duties with a suitable measurement sequence.
