THE BASICS OF KARL FISCHER TITRATION Karl Fischer titration is an analytical technique to measure the amount of water contained in various samples, which may be solid, liquid or gaseous. This method was originally developed in the 1930s by German chemist Karl Fischer. Karl Fischer titration is based on a 1:1 reaction between iodine and water in .KF-Titration Die volumetrische KF-Titration ist die „klas-sische“ Karl-Fischer-Titration. So hat Karl Fischer die Glasbürette für sein Pyridin enthaltendes Re-agenz als genaue Dosiermöglichkeit verwendet. Dieses Reagenz enthielt genauso wie die heu-tigen Reagenzien Iod, das nach Gleichung 1 mit dem Wasser reagiert.A small quantity of sample, accurately weighed or measured, is introduced into the vessel using a glass syringe or pipette. In the case of coulometric titration, the titration cell is assembled, and the titration process is initiated. [3] The titration proceeds by slowly adding the Karl Fischer reagent to the sample solution and stirring .
The Coulometric Karl Fischer Titration Method is usually best suited for samples with an expected Water Content across the full range from 0.0% - 100.0% and offers a much higher accuracy compared to the Volumetric Karl Fischer Titrator, hence the Coulometric Karl Fischer Titrator is also suitable for samples with a very low Water Content below 1%.However, iodine is generated electrochemically by anodic oxidation in the coulometric cell according to the following Karl Fischer titration formula half-reaction: 2 I - -> I 2 + 2 e Current is applied to the solution until the species is either oxidized or reduced to a new state as indicated by a dramatic shift in potential. Coulometric Karl Fischer titration cells having a current generator with a ceramic diaphragm, separating the anodic and the cathodic compartment, as well as diaphragm-free cells, are commercially .Coulometric water content determination according to Karl Fischer Page 1 of 5 Application Bulletin 137/6 e Coulometric water content determination according to Karl Fischer .
