  • Ion Selective Electrodes: YSI TruLine ISEs
  • 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∗ 푅푅푅푅 푛푛푛푛 -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 푆푆푆푆푆푆푆푆푆푆 Ca2+=2.303∗ 8.314 퐽퐽 퐾퐾 푚푚푚∗298.15 퐾퐾∗ 12∗ 푚푚푚9.649∗104 퐶퐶 =2.958∗10−2 퐽퐽 퐶퐶−1=29.58 푚푚푚푚
  • 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
  • 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
