Electrochemistry Theory
Ion Selective Electrodes – Theory
An Ion selective electrode is an electrochemical sensor that produces a potential in millivolts between itself and a reference electrode.
Methods of Analysis by ISE
Unlike a pH electrode an ISE is not just dipped into a solution and a direct readout obtained.
Automatic Temperature Compensation for ISE’s
We are all used to measuring pH and conductivity and achieving a result that is corrected to be the same as the actual result would be at 25 degrees centigrade.
Magnetic Stirrers and ISEs
Most ISE work involves mixing standards and samples with ISABs or performing a dilution. Your samples and standards should therefore be mixed thoroughly.
Quick Ion Analysis
To measure the concentration of any Ion in samples is traditionally quite expensive as you need to purchase an ION meter. However if you are looking for a quick, easy and cost effective method this excel calculator is for you.
Ionic Strength Adjustment Buffers (ISAB)
To make sure the ionic strength is similar in all standards and samples add a known volume of ISAB to a known volume of each standard and sample.
