Karl Fischer Moisture Analyzer

Karl Fischer moisture analyzer is used to determine the moisture content of samples. There are two methods that can be used in Karl Fischer titration: volumetry, in which the amount of reagent that has been used determines the amount of water; and coulometry, in which an electrolysis reaction occurs and the amount of electricity used tells us the amount of water in the sample. Volumetry is appropriate to detect water amounts from 1 to 100 milligrams, while coulometry is the better choice for very small amounts of water, from 10 micrograms to 10 milligrams.
