Measurement Basics: Nernst Equation

• ISEs measure ion activity (i.e. “effective concentration”) -Ion activity < actual ion concentration due to interaction of ions in solution, reduces ions available to react

• ISEs are designed to measure specific ions, but other ions can interfere

-Adding ionic strength adjustor acts to minimize/mask effect of interfering ions

• pH electrode is a Hydrogen ISE

• ISE output is in mV; follows Nernst Equation

• Slope of electrode: 2.303 ∗ 𝑅𝑅𝑅𝑅𝑛𝑛𝑛𝑛

-Divalent (e.g. Ca2+) ~ 29 mV/decade (typical 26-29)

-Must have decade (i.e. order of magnitude) difference in calibration standards; can “fill-in” between standards if many used

Page 18: TruLab, MultiLab and ISEs for Laboratory Measurements | YSI

ISE Electrode Types

Half cell ISEs:

• Contain only the ion sensor (half cell); separate reference must be used

-Both have ion exchange with the sample

-mV output determined by difference in potential b/w the sensing half cell and the reference

Combination ISEs:

• Contain the sensing electrode and reference electrode in the same body

• Much easier to use; preferred by most customers

• YSI TruLine electrodes

Page 19: TruLab, MultiLab and ISEs for Laboratory Measurements | YSI

Measurement Methods

Direct measurement:

• Simple and most commonly used ISE method

• Measure mV output in samples and determine concentration based on calibration (i.e. just as is done with pH)

Incremental methods:

• Standard addition, standard subtraction, sample addition, sample subtraction

• Methods of spiking the sample

• Sample ion concentration calculated from change in potential

• YSI TruLab 1320 and MultiLab 4010-2/3 have all incremental methods preprogrammed

TruLine ISE Tips

• Takes ~1-2 mL to fill electrode

• One order of magnitude (i.e. decade) difference between two standards; can include standards between

• Add ISA to both samples and standards to ensure similar ionic strength

• Short term (1-3 day) storage: place in low standard and fill the reference

• Long term: store dry (i.e. drain reference) and avoid sunlight

• Fill hole should be open during calibration and measurement, closed during storage
