Application
Zeta Potential -Colloidal Silica is intended primarily to assessing the performance of instrumentsand/or methods used to measure zeta potential and electrophoretic mobility.
Features and Benefits
- Accompanied with certified values of electrophoretic mobility and zeta potential, values are metrologically traceable to the SI unit and measured using electrophoretic light scattering technique.
- The non-certified value of conductivity is reported.
- The NIST certificate is provided with period of validity, storage, safety, handling,use, and maintenance instructions.
Other Notes
Please download a current certificate at nist.gov/SRM for current analytes and certified values.
