Summary
The disadvantages of conventional titration cells for the coulometric Karl-Fischer-titration, long preelectrolysis times, unstable and relatively high blank currents and the sample injection with syringes, are eliminated by means of a new measuring cell concept. The complete filling of all cell compartments with electrolyte and the integrated injection valve contribute essentially to the improved precision and accuracy in the determination of small water amounts.
