What is coulometric Karl Fischer titration? Coulometric titration is used to determine trace-levels of water in samples within a range of 10 µg to 200 mg water. However, larger amount of water (> 10 mg) require a lot of time and/or may exceed the water capacity of the KF reagent, which could lead to incorrect results.Whatever your requirements – we have the right Karl Fischer titrator for you 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%.

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 .A Karl Fischer titrator. 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. [1] [2] Today, the titration is done with an automated Karl Fischer titrator. E.
