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.
