The range of KF titration reagents was completed with the addition of Hydranal-Water Standards (section 2.5), titration reagents for back titrations and buffering substances
The volumetric Karl Fischer titration is used for samples with a water content greater than 1% in solid and liquid samples. As the name indicates, the amount of water is determined by volumetry, based on a redox reaction . Volumetric Karl Fischer titration Coulometric Karl Fischer Titration. Panreac Applichem 4 Pyridine-freeA Karl Fischer titrator. In analytical chemistry, Karl Fischer titration is a classic titration method that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer. [1] [2] Today, the titration is done with an automated Karl Fischer titrator.

Get Contact details & address of companies manufacturing and supplying Karl Fischer Titrator, KF Titration, Coulometric Titrator across India.Coulometric Karl Fischer titration is preferred for very low levels of water contents (below 1%) or for water determination of expensive substances with small sample amounts. Compared to volumetric titration, the iodine titrant required for the titration is electrochemically generated in the titration cell itself by anodic oxidation of iodide .MM: We recommend carrying out a volumetric or coulometric Karl Fischer titration using a certified standard as a sample. In volumetry, a threefold titer determination followed by a determination of a different standard is carried out and the recovery of the water content in the determination of the standard is calculated.
What is coulometric Karl Fischer titration? Coulometric titration is used to determine trace-levels of water in samples within a range of 10 µg to 200 mg water. However, larger amount of water (> 10 mg) require a lot of time and/or may exceed the water capacity of the KF reagent, which could lead to incorrect results.
