The coulometric titration cell is filled with 100 mL KF reagent. If a generator electrode with diaphragm is being used, it is filled with approx. 5 mL catholyte solution. The stirring rate should ensure that the reagent is well mixed.
In combination with an oven, the titration cell is filled with 150 mL KF reagent. Apart from that, we recommend using the maximum stirring rate for these measurements.
