Application report: New DIN/EN standard for the determination of anionic surfactants using potentiometric two-phase titration


The standard DIN EN 14480 describes the determination of anionic surfactants by potentiometric two-phase titration. The use of unproblematic solvents, the short determination time of only a few minutes, and the objective determination of the equivalence point using potentiometry make the two-phase titration a precise, rapid, and healthier alternative to the previously widely used Epton titration in accordance with ISO 2271.
