Materials and methods
Test guideline
- Guideline:
- other: Internal Intertek method, SOP 043.01/5
- Deviations:
- not specified
- GLP compliance:
- not specified
- Details on methods and data evaluation:
- A very small amount of sample was dispersed in deionised water to achieve a very pale brown coloured liquid suspension, and sonicated for 10 minutes.
The dispersed sample was analysed by Malvern Zetasizer Nano-ZS ZEN3600 - LIMS1951. Five measurements were carried out and the average zeta potential is calculated.
