Introduction to Ion Measurement
An Ion-Analyser or Ion Meter is required to
convert the electrical signal from the ISE into a
relevant unit of concentration (ppm or mol/litre).
Ion-selective Electrodes (ISEs) allow us to
determine the concentration of a specific ion in
aqueous ( in rare cases non-aqueous) solutions.
Measurements with ISEs are temperature sensitive.
An exact temperature compensation for
measurements taken at different temperatures is
not possible. Therefore, calibration and sample
measurement should be done within the same
temperature range (/- 10).
The measurement made is not an absolute one but
rather a comparison of a sample measurement with
a calibration measurement (calibration curve)
The calibration procedure uses Ion-Standards
(solutions with a precisely defined ion
concentration) and specifically diluted
calibrating solutions. Usually, 110 serial
dilutions from a 1000 ppm ion-standard.

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.
• 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
