Understanding Karl Fischer (KF) Water Determination

Karl Fischer (KF) titration is widely recognized as the most selective and precise method for determining water content in various samples. This method offers two primary techniques: volumetric and coulometric titration.

Volumetric Method

In the volumetric method, iodine is precisely added using a piston burette. This method is suitable for analyzing liquid, solid, or gaseous samples. By selecting the appropriate KF reagents and adjusting conditions like temperature or using a disperser, accurate water content determination can be achieved across a range of sample types.

Coulometric Method

The coulometric method generates iodine directly within the titration vessel, enabling the detection of very low water concentrations. An advantage of this method is that there is no need to determine the concentration of the titrant. For direct titration in glass vessels, samples must be liquid or gaseous. Solid or highly viscous samples require external dissolution or extraction, which can be done using equipment like the TO 7280 headspace oven or TO 7280/TW 7650 oven with autosampler.
