Analysis of surfactants with potentiometric titration

From shampoo and toothpaste to detergents and disinfectants – surfactants are an integral part of many consumer products. They are usually tested in the QC laboratory using potentiometric titration.

Key learnings of this webinar:

  • What are surfactants and why are they important?
  • How to reliably determine cationic, anionic, and non-ionic surfactants by potentiometric titration
  • The difference between an aqueous surfactant tiration and a two-phase surfactant titration and when to prefer which
  • How two-phase surfactant titration can be used as an alternative to well-known Epton Titration
  • Which potentiometric sensor to choose for which titration
