The Karl Fischer method is commonly used for water content determination in research and development, quality control and production monitoring. It is easily applied to a huge variety of samples in various industries, including potato chips or cheese in food and beverage manufacturing and aspirin or salicylic acid in pharmaceutical production.
However, water content determination through Karl Fischer titration is possible only if the water inside the samples is freely available. This is not the case with solids if the water is bound (e.g., as entrapped water, water of crystallization, or capillary-bound water). Thus, suitable sample preparations and special methods are necessary to correctly release water in these samples.
