Karl Fischer (KF) titration is a widely accepted method for determining the water content in a sample, with volumetric Karl Fischer titration being the most used technique, measuring water content from 100 ppm to 100%. However, achieving accurate results can be challenging, as several factors can influence the outcome. As such, it is crucial to pay careful attention to specific details when performing the method to ensure reliable and precise titration results.
