- AN-K-074Water content in crude oil determined with Karl Fischer titration
To determine water in crude oil, ASTM D4928 recommends coulometric Karl Fischer titration with the oven method, allowing full automation for high reproducibility.
- WP-089Water content determination in ketones using Hydranal™ NEXTGEN FA reagents
With Hydranal™ NEXTGEN FA reagents, the water content in ketones can be determined quickly and reliably. Compared to other existing KF reagents for ketones on the market, the side reactions are measurably better suppressed.
- TA-061Two webinars on Karl Fischer titration: Fundamentals and Troubleshooting
Karl Fischer titration performs specific and precise water determinations. This is why it is numbered among the most frequently used laboratory methods throughout the world. The accompanying articles for the two webinars on basic principles and troubleshooting with respect to titration summarize certain core information that they contain, including among other subjects the handling of electrodes, the conditioning of titration cells and the significance of drift for Karl Fischer titration.
- AN-K-073Volumetric Karl Fischer titration with Scharlau Aquagent® reagents
Test measurements on water standards are performed with an OMNIS KF Titrator and Karl Fischer reagents Aquagent® Complet 5 and Methanol Fast from Scharlau.
- WP-084Quality control of analytical parameters in battery production
Lithium-ion batteries (LIBs) are the most common rechargeable options available today. Production of LIBs needs to follow stringent quality standards.
- AN-K-052Determination of the water content in sodium acetate with MATi 10
In this application note, Karl Fischer titration is used to determine water content in sodium acetate trihydrate. The MATi 10 allows this determination to be automated, saving users time in the laboratory.
- AN-K-044Water in panthenol
The water content in panthenol is determined according to Karl Fischer.
- AN-K-036Water in vinyl chloride (chloroethylene)
The water content of vinyl chloride is determined according to Karl Fischer.
- AN-K-028Water in color paste
The water content of color paste is determined according to Karl Fischer.
- AN-K-020Water in flour (meal)
The water content of flour is determined according to Karl Fischer. To shorten the analysis times and to obtain more precise results, the determinations are carried out at 50 °C.
