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.
Karl Fischer titration is the specific standard method for the determination of water content and gives accurate and precise results within minutes. With METTLER TOLEDO Karl Fischer titrators your operators need only to press one button to run a water determination!
Our portfolio of Karl Fischer titrators includes compact all-in-one options for routine moisture determination as well as fully automated Karl Fischer systems for volumetric and coulometric Karl Fischer titration of water contents from 0.001 to 100%.
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.
The principle of Karl Fischer titration is based on the redox reaction between iodine and sulfur dioxide in presence of water. Water reacts with iodine and sulfur dioxide to form sulfur trioxide and hydrogen iodide. An endpoint is reached when all the water present in the sample is consumed.
