- 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.
- AN-K-039Water in penicillin-G-potassium
This application note describes the water content determination in penicillin by using volumetric Karl Fischer titration. Unwanted side reactions can be avoided by using special solvent mixtures.
- AN-K-022Water in pesticide formulations
This Application Note describes the determination of water content in pesticides using Karl Fischer titration.
- AN-K-005Water in ink
Determination of water content in ink is possible with Karl Fischer titration, as shown in this Application Note.
- 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.
- WP-023Karl Fischer titration and near-infrared spectroscopy in perfect synergy
Metrohm has shaped moisture analysis for more than half a century. Find out about new developments in water analysis and learn how near-infrared spectroscopy in combination with Karl Fischer titration can increase your sample throughput and boost your productivity.
- AN-K-043Water in aniline
The water content of aniline is determined according to Karl Fischer in buffered solvent.
- AN-K-002Water in methyl ethyl ketone peroxide (butanone peroxide)
The water content of methyl ethyl ketone peroxide is determined according to Karl Fischer using two-component reagents in order to prevent unwanted side reactions. (Separate solvent is used to ensure a high excess of sulphur dioxide and amine in the titration vessel.)
- AN-K-045Water in methylcyclohexane
The water content in methylcyclohexane is determined by coulometric Karl Fischer titration.
- AN-K-010Water in coal dust
The water content of coal dust is determined according to Karl Fischer. Because of the low water content of the voluminous sample, the oven method (nitrogen, 270 °C) and coulometric titration have to be used.
