THE BASICS OF KARL FISCHER TITRATION Karl Fischer titration is an analytical technique to measure the amount of water contained in various samples, which may be solid, liquid or gaseous. This method was originally developed in the 1930s by German chemist Karl Fischer. Karl Fischer titration is based on a 1:1 reaction between iodine and water in .Karl Fischer (KF) titration is a specific moisture determination technique widely used by industry and scientists. The different ways of producing iodine can be divided into the coulometric method and the volumetric method. Karl Fischer Titration Principle The coulometric Karl Fischer titration is concerned with the determination of traces of water from e.g. 10 ppm up to 1-5% content in the most different samples such as in petroleum products .
