can be estimated using the formula: FCV/KF in which F is the water equivalency factor of the Reagent, in mg per mL; C is the used volume, in percent, of the capacity of the buret; V is the buret volume, in mL; and KF is the limit or reasonable expected water content in the sam...
The Principle of Water-Content Determination by Karl Fischer Titration In 1935, Karl Fischer (KF) proposed a titration method for water content determination. Since then, KF titration has been extensively applied in the determination of water in various samples, including liquids, solids, and gases...

4a, where the sensor provides the highest output and the maximum detection range with the DI content of 1.5 vol%. The detailed explanation of the principle of water content selection are demonstrate in Figs. S19, S20 and S21 and Note S3. The optimal GBM-IR PDMS-based triboelectric sensor...
The determination of the water content in cannabis is of great importance for the qualitative assessment of the active components (THC, CBD) as well as its storage stability.Karl Fischer titrationoffers a selective and reliablealternative to the drying method. Compared to the reference method of na...
The most attractive measurement methods for water content used at, e.g., CHP plants are working on the in-line/on-line principle. Sensors are installed in-line directly at the processing, e.g., at a conveyor belt transporting the biomass to the boiler or connected intermittently or continuou...
After every week, a sample was withdrawn and its water content was measured using Karl-Fischer titration (Mettler Toledo-C20 Compact KF coulometer) until a constant value was reached. This was the case after about 15 days. 3. Results and Discussion 3.1. Drying Requirements To avoid the formati...
