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 .
Tips and tricks to completely release water from samples using internal extraction, external extraction and Karl Fischer oven method for accurate determination of water content by Karl Fischer titration method.
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 principle of Karl Fischer titration is based on the oxidation reaction between iodine and sulphur dioxide. Water reacts with iodine and sulphur dioxide to form sulphur trioxide and hydrogen iodide.
This Karl Fischer Titration Guide Part 1 explains the chemical reaction and the two major measuring techniques: volumetry and coulometry. It also presents a short, historic overview of the development of Karl Fischer’s method.
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).
Sep 10, 2022 · Karl Fischer titration can be defined as an analytical technique that uses coulometric or volumetric titration to determine a trace amount of water in a sample quantitatively.
A defined, reliable and truly practical method for water measurement was introduced in 1935 when chemist Karl Fischer (KF) published his manuscript “New procedure for the determination of the water content in liquids and solids.” (K. Fischer; Angew. Chemie 1935, 48, 394). Karl Fischer titration, as it was to be known, could be followed
Mar 3, 2020 · What is the Karl Fischer method and what is it used for? The Karl Fischer method is an analytical technique for the determination of the water content in a liquid or solid sample by titration.
Karl Fischer titration is a widespread method used in quality and in-process control, production, research, and development to determine the amount of water in solid, liquid, or gas samples.
