Monograph: Water determination by Karl Fischer Titration

8.108.5089

  • Feature overview

Measuring water content is an essential technique for most laboratories, on par with pH measurement, weighing, and acid-base titration. The main techniques for determining water content are drying methods (such as drying ovens or infrared balances) and the Karl Fischer (KF) titration, known for its specificity and speed. This monograph provides readers a comprehensive guide to the Karl Fischer titration method.

Key points presented are:

  • Learn about Karl Fischer reagents and the chemical reaction behind the Karl Fischer titration.
  • Volumetry and coulometry are the two methods used in Karl Fischer titration. Learn about their differences and when to use which method.
  • Side reactions can affect the accuracy of KF titrations. Learn about the different interfering substances and suitable measures to suppress the side reactions.
  • Sample preparation is essential for accurate water determination. Techniques presented include solvent extraction and homogenization.
  • Applications: KF titration is used for water determination in various samples, including raw materials, cosmetics, drugs, foodstuffs, biological samples, petrochemical products, plastics, paints, lacquers, solvents, and gaseous samples.
