Karl Fischer Volumetric Titration

Karl Fischer Volumetric Titration is one of the official methods utilized to determine moisture content with extreme accuracy and is widely employed in various industries and research endeavors. This technique has earned a reputation for its reliability and precision in quantifying the moisture present in diverse materials, including solids, liquids, and gases.

Principle of Operation

• Karl Fischer Volumetric Titration leverages a chemical reaction between iodine and water in the presence of a base and an alcohol. The reaction consumes water molecules present in the sample, reducing the concentration of iodine in the solution.
• During the titration, iodine is generated electrochemically, and the equivalence point is reached when the first excess of iodine is detected by the instrument. This point signifies the complete reaction of all water present in the sample.
• The moisture content of the sample is then calculated based on the volume of titrant consumed until the equivalence point, which corresponds to the water content present in the sample.

Advantages of Karl Fischer Volumetric Titration

• Highly accurate and reliable technique
