Webb26 jan. 2024 · This test method also covers the indirect analysis of water thermally removed from samples and swept with dry inert gas into the Karl Fischer titration cell. Mercaptan, sulfide (S – or H 2 S), sulfur, and other compounds are known to interfere with this test method (see Section 6). WebbWater standard oven 1% is used as certified reference material to check the accuracy of coulometric and volumetric water determinations, according to ISO 9001 chapter 7.1.5 “Monitoring and measuring resources”, using Karl Fischer oven and thermobalances. But its low water content of 1% makes it particularly suitable for water determinations ... Karl Fischer titration is a classic titration method in chemical analysis that uses coulometric or volumetric titration to determine trace amounts of water in a sample. It was invented in 1935 by the German chemist Karl Fischer. Today, the titration is done with an automated Karl Fischer titrator.
