Determination of water content
WebFAQ - Water determination according to Karl Fischer. Can a Karl Fischer coulometer also be used up to 100% water content? The coulometric method can also determine up to 100% water. However, at 10 .000 µg (10 mg) the titration already takes quite a long time. Therefore, no more than 5,000 µg (= 5 mg) of water should be weighed in. Webratus is designed for accurate determination of moisture content. • The endpoint is determined potentiometri-cally, and the titration burette is controlled by a solenoid-operated valve, which closes when the endpoint is reached. Coulometric Karl Fischer Determination • Best suited for materials with less than 1% water
