The NEW 860 KF Thermoprep opens up new possibilities for determining the water content by the Karl Fischer method of samples that are either insoluble, react with the KF reagent or which cannot be placed directly in the titration vessel for other reasons. The samples are no longer placed in the oven in weighing boats, but each sample is now contained in its own tightly sealed sample vial.
The 860KF can be used with all volumetric and coulometric KF titrators.
Water determination of “difficult†samples can now be achieved, as the sample is not put directly into the titration cell.
Examples of difficult samples include, oil (containing additives), plastics, paint, pharmaceutical products, hair, wound-care products, to name but a few.
The 860 KF Thermoprep from Metrohm drives off moisture from solid
and liquid samples for the subsequent coulometric or volumetric determination of the water content by the Karl Fischer method.
Temperature range 50...250 °C
The 860 KF Thermoprep is available in 3 options: Option 1 is as an oven
on it’s own. Option 2 is as an oven in conjunction with a coulometric KF
(for low level water), and option 3 is with a volumetric KF (for high level water).
