What is the difference between volumetric and coulometric Karl Fischer titration?
Volumetric Karl Fischer titration involves measuring the volume of titrant needed to react with the water in a sample, while coulometric Karl Fischer titration involves measuring the amount of electricity needed to generate the iodine necessary to react with the water in the sample. Coulometric titration is generally more precise and accurate for low-level water content determination.
What types of samples can be analyzed using volumetric KF titration?
Volumetric KF titration is suitable for solid, liquid, and gaseous samples as long as the water can be released from the sample in the KF solvent.
Why is water content determination important in gases?
Water vapor can affect the properties of the products and the industrial processes whenever gases are involved. For instance, water vapor present in natural gas may affect the storage of gas and its transport through distribution mains.
What is the method of choice for the determination of the water content in non-explosive and non-flammable gaseous samples?
Karl Fischer titration represents the method of choice for the determination of the water content in non-explosive and non-flammable gaseous samples.
