Introduction to Ion Measurement Ion-selective Electrodes (ISEs) allow An Ion-Analyser or Ion Meter is us to determine the concentration of a required to convert the electrical specific ion in aqueous (& in rare signal from the ISE into a relevant cases non-aqueous) solutions. unit of concentration (ppm or mol/litre). Measurements with ISEs are temperature sensitive. An exact temperature compensation for The measurement made is not measurements taken at different an absolute one but rather a temperatures is not possible. Therefore, comparison of a sample calibration and sample measurement measurement with a calibration should be done within the same measurement (calibration curve) temperature range (+/- 10). The calibration procedure uses Ion- Standards (solutions with a precisely defined ion concentration) and specifically diluted calibrating solutions. Usually, 1:10 serial dilutions from a 1000 ppm ion-standard. NICO 2000 LTD. Typical ISE Calibration Graph NB: X-axis units are the logarithm of the Molar Activity of the Ion NICO 2000 LTD. ISE Measurement with ELIT ISE/pH Ion-Analyser For educational purposes, sample results are plotted on the Calibration Graph NICO 2000 LTD. pH Measurement with ELIT ISE/pH Ion Analyser • pH is a measure of the Acidity or Alkalinity of a solution. • Actually measures the concentration of Hydrogen Ions. 2-Channel pH Display “Virtual Instrumentation” • Is based on a logarithmic relationship between the sensor • signal (mV) & the Hydrogen ion concentration (mol/L). • Calibration standards for pH measurements are called • Buffers due to their ability to keep the pH value stable when small amounts of acid or alkaline substance added. • The most common Buffers are pH 4, pH 7 & pH 10. • Like all Ion-selective measurements, pH measurements are influenced by temperature changes. Therefore, instruments have manual or automatic temperature compensation facilities. • To simplify the handling of results of pH measurements, the 14 decades of hydrogen ion concentration are converted into a linear (pH) scale from 0 to 14 using the Soerensen equation: pH value = negative Logarithm of the Hydrogen ion concentration. pH 0 is extremely acidic, pH14 is extremely alkaline & pH 7 is neutral.
