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.
