Accuracy and precision is improved further if the titrant is not added with a burette, but produced directly in the solution with a current applied by a generator cell. This also makes a titrant concentration determination obsolete. The Compact coulometric Karl Fischer Titrators offer particularly fast and precise titration of samples with a low water content from 1 ppm to 5%. The titration vessel is made completely from glass which ensures a uniquely low drift and hence makes the most accurate and precise results possible
In the Service department of an engine producer, all oils, lubricants and fuels used in the engine are tested for water content. If the result exceeds 500 ppm (0.05%), the parts in contact with the liquid are checked for corrosion. The simple water content determination saves significant time and money, as only the risky parts need further investigation. The prevention of corrosion protects the engine from failure, which is crucial, for example, in aircraft.
The Volumetric Compact Karl Fischer Titrators have been designed for a wide range of water content applications: determinations from 100 ppm to 100% water – fast and precisely. The titration vessel is optimized to retain a low drift value and offers the possibility to determine the water content of liquid, solid and gaseous samples.
Fast results and direct operation with large Touchscreen: The Coulometer keeps the user informed on the cell condition and makes all tasks (e.g., sample and drift determination) available to be started with One Click®. If the expected water content is known, the optimum sample weight can be calculated. The Online Screen offers all ongoing information for the titration and direct access to all data and tasks that further accelerates thec omplete workflow
Most convenient without diaphragm: Handling of different reagents for catholyte and anolyte can be complicated and expensive. For most samples the generator cell without diaphragm offers more convenience in use. No catholyte is needed and the anolyte can be exchanged with the Solvent Man-ager on One Click®. Only a few samples still require a cell with diaphragm, which is clearly ex-plained in the METTLER TOLEDO applications brochure.
Always in good shape thanks to Reagent Control: The reagents play an importantrole in the coulometric Karl Fischer titration. The Reagent Control keeps an eye on the important param-eters so that once the maximum capacity is reached the user is prompted to replace the reagents. Contact with any of the reagents is avoided and the user always has an optimal system, ready to use and prepared to generate correct, repeatable results
