FAQ | Titration
|Up to which water content can volumetric KF titrators be used (bottom limit)?
||The bottom limit depends on the type and volume of the sample. In practice, the volumetry is used for water volumes of > 100 ppm.
|Can a KF Coulometer also be used for a water content of up to 100%?
||This method can also determine 100% water. At 10,000 µg (10 mg) the titration will take a long time. Therefore, the user should not weigh in more than 5,000 µg (= 5 mg) water (one drop of water contains about 35-50 mg of water!).
|Application areas for coulometric or volumetric KF titration?
||Coulometry is used to determine µg volumes of water in gaseous or liquid samples without side effects/reactions. Volumetry is used to determine mg volumes of water in gaseous, liquid or solid samples.
|When should a coulometry with a diaphragm be conducted?
||The usual application takes place with the cell without a diaphragm. For very small water volumes (< 50 ppm), the diaphragm cell can be advantageous depending on the application.
