karl fischer volumetric vs coulometric
The determination of the water content according to Karl Fischer is nowadays performed by two different techniques: Volumetric Karl Fischer Titration, where a solution containing iodine is .over-titration. However, volumetric titrators sometimes show zero drift for a short time without being over-titrated. If you have a real excess of iodine in the titration cell, the result of the next determination will most probably be wrong. Therefore, over-titration should be avoided. There are various possible reasons for over-Coulometric Karl Fischer Reagents Coulometric titration is typically selected for samples with a water content of less than 1%, although samples with water contents up to 5% are possible. Anolyte and catholyte choices are based on .

The results in volumetric Karl Fischer titration are fluctuating – what are the reasons? Possible reasons: Improper stirring time and speed, if the stirring speed is too slow, the titration may also be too slow, irregular and over titration may occur. If stirring speed is too high then bubbles are formed in the solution which can falsify the . The volumetric titrator performs the following three key functions: 1) It dispenses KF titrating reagent containing iodine into the cell using the burette 2) It detects the endpoint of the titration using the double platinum pin indicator electrode 3) It calculates the end result based on the volume of KF reagent dispensed using the onboard .
