Surf PAC Methods

The methods delivered with the Surf PAC package can easily be loaded into the following Metrohm Titrino models:

• With the 798 MPT Titrino and 799 GPT Titrino (also applies to 751 GPD Titrino with instrument program version 5.751.0020 or higher and 785 DMP Titrino) you use the methods memory card included in the package to load methods into the Titrino.
  
• With 794 Basic Titrino (also applies to 716 DMS Titrino, 736 GP Titrino and 751 GPD Titrino with instrument program version earlier than 5.751.0020) you use a PC and the demo version of Metrodata VESUV 3.0 contained in the package.

Or load the methods directly into a Titrando and let the method converter transform the methods for you.

Overview of the Surf PAC Methods

A - Anionic Surfactants

1. Titer determination of cationic titrants for the potentiometric two-phase titration of anionic surfactants and soaps
2. Titer determination of the cationic titrant for the potentiometric aqueous titration of anionic surfactants
3. Anionic surfactants and soaps in washing powders by potentiometric two-phase titration
4. Anionic surfactants in oil-containing shower gels or bath additives by potentiometric two-phase titration
5. Anionic surfactants in dishwashing concentrates by potentiometric aqueous titration

B - Cationic Surfactants

6. Titer determination of the anionic titrant for the potentiometric two-phase titration of cationic surfactants
7. Titer determination of the anionic titrant for the potentiometric aqueous titration of cationic surfactants
8. Cationic surfactants in hair conditioners by potentiometric two-phase titration
9. Cationic surfactants in cooling lubricant concentrates by potentiometric two-phase titration
10. Cationic surfactants in mouth rinses by potentiometric aqueous titration

C - Non-ionic Surfactants

11. Non-ionic surfactants; calibration factor with Triton X-100 and polyethylene glycol 1000
12. Non-ionic surfactants in household cleaners
13. Non-ionic surfactants in wool shampoo

D - Betains and Polyacrylates

14. Betains by aqueous titration with sodium tetraphenylborate and by non-aqueous titration with perchloric acid
15. Polyacrylates by titration with TEGO trant A100

E - Further Ingredients in Formulations
