A Karl Fischer titrator, also known as a KF titrator, is used to determine the amount of water in a sample. Because the presence of water can affect many characteristics of a product, including reactivity, stability, and quality, KF titration is important to and is used in many industries. Food, oil, pharmaceutical, and semiconductor industries all use Karl Fischer titrators to maintain the quality of their products. There are two methods that can be used in Karl Fischer titration: volumetry, in which the amount of reagent that has been used determines the amount of water, and coulometry, in which an electrolysis reaction occurs and the amount of electricity used tells us the amount of water in the sample. Volumetry is appropriate to detect water amounts from 1 to 100 milligrams, while coulometry is the better choice for very small amounts of water, from 10 micrograms to 10 milligrams. When choosing the right Karl Fischer titrator, several factors should be considered, including sample size needed, if volumetric or coulometric titration is needed, time the titration will take, and how much of the process is automated and how much needs to be done by hand.

Built-in magnetic stirrer The 899 Coulometer does not need much space because it has its own magnetic stirrer built in. There is no need for a support rod either. An integrated holder keeps the titration cell safely standing on the upper side of the instrument.
Independent power supply No socket around to plug in the power cord? No problem with the 899 Coulometer. In this case, users can rely on the instrument’s independent power supply that comes with an optional Power Box containing a set of rechargeable batteries. This means users can perform coulometric determinations of the water content almost anywhere they want!
Automation possible At the same time, the 899 Coulometer provides the capabilities of a full-grown Metrohm Coulometer. Thus, it can be linked to a manual oven (860 KF Thermoprep) or to an 885 Compact Oven Sample Changer for fully automated thermal sample preparation and subsequent coulometric determination of the water content....
