The Basics of Karl Fischer Titration
From the reaction mechanism, it's evident that the reagent used for the titration needs to contain the following: Alcohol methanol was used originally, but in different variations of the reagent can be replaced by ethyl carbitol, methoxypropanol, ethanol, etc. Sulfur dioxide Iodine Base pyridine was used initially, but has since been replaced by imidazole, which assures a higher rate of reactio...
متن کاملWater Determination in Bee Products Using the Karl Fischer Titration Method
One of the most widely used techniques for water content determination in food is Karl Fischer (KF) titration. Compared to other methods based on loss of weight, the primary advantage of the Karl Fischer titration method is its high selectivity to water. The aim of the study was to develop and validate the Karl Fischer method for moisture determination in pollen loads, royal jelly, bee venom an...
متن کاملSimple Modification of Karl-Fischer Titration Method for Determination of Water Content in Colored Samples
The most commonly used technique for water content determination is Karl-Fischer titration with electrometric detection, requiring specialized equipment. When appropriate equipment is not available, the method can be performed through visual detection of a titration endpoint, which does not enable an analysis of colored samples. Here, we developed a method with spectrophotometric detection of a...
متن کاملMeasuring water content of feces by the Karl Fischer method.
We describe a technique for measuring the water content of stools by the Karl Fischer method. The analysis is based on removal of water into a mixture of methanol/chloroform (1/2), after dispersion of the stool by sonication in presence of solvent. An aliquot of the solution thus obtained is placed in themeasuring cell of a Karl Fischer apparatus and then analyzed in the classic way. We further...
