Karl Fischer Titration is a widely-accepted technique used to accurately determine the moisture content of various substances. It is a highly precise analytical method employed in a diverse range of industries, including pharmaceutical, chemical, and food manufacturing.
Principle of Karl Fischer Titration
Karl Fischer Titration relies on a chemical reaction between water and iodine in the presence of a suitable solvent and a base. The reaction proceeds until all the water present in the sample has been consumed. The amount of iodine consumed during the titration corresponds directly to the moisture content of the sample.
Applications of Karl Fischer Titration
