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 .
Karl Fischer titration is a titration method that uses volumetric or coulometric titration to determine the quantity of water present in a given analyte. This method for quantitative chemical analysis was developed by the German chemist Karl Fischer in the year 1935, Today, specialized titrators (known as Karl Fischer titrators) are available ...
Karl Fischer titration is a widely utilized analytical method specifically designed to determine the moisture content in various substances. This titration technique relies on a chemical reaction between iodine and sulfur dioxide with water, a reaction integral in quantifying moisture levels accurately. [1-4]
The Karl Fischer method for water content determination is one of the most frequently used titration methods. Published by German petrochemist Karl Fischer in 1935, it has become well renowned for a wide variety of applications and samples.
Karl Fischer titration for water determination is probably the best known and most widely used titration method. The reaction mechanism is well explored and there is a broad offering of suitable reagents and instruments to be used.
Jul 19, 2023 · Karl Fischer (KF) titration is a widely used technique for moisture or water determination in solid, liquid and gaseous samples.
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.
The Karl Fischer titration is a moisture determination method specific for water and is suitable for samples with a high water content (titrimetry) and also for those with water content in the ppm range (coulometry).
What is the Karl Fischer Method? As shown in Formula (1) below, the Karl Fischer method uses Karl Fischer reagent, which reacts quantitatively and selectively with water, to measure moisture content. Karl Fischer reagent consists of iodine, sulfur dioxide, a base and a solvent, such as alcohol.
Hoffmann investigated ways to improve Karl Fischer titration, making it safer, more accurate, easier to use and applicable to a wider range of substrates. These improvements became the foundation of the Hydranal™ product line described in this Manual. Three important innovations define the Hydranal line:
