The Karl Fischer Titration is a titration method for measuring water content in basically all types of substances. It was invented in 1935 by the German chemist Karl Fischer. The Karl Fischer Titration is based on an iodine / iodid .Karl Fischer titration is a widely used analytical method for quantifying water content in a variety . Coulometric KFT In coulometric Karl Fischer, iodine is generated electrochemically in situ during the titration. Water is quantified on the basis of the total charge passed (Q), as measured by current (amperes) and time .• For volumetric Karl Fischer titration, linear titra-tion is a function of the instrument performance, rather than the sample analysis method, and therefore linearity experiments are deemed un-necessary. For coulometric Karl Fischer titration, the qualitative relationship between the current and

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 .
