Scientific Basis: Helmholtz-Smoluchowski Equation
The Zeta Potential Calculator uses the Helmholtz-Smoluchowski equation, a peer-reviewed method for calculating zeta potential from electrophoretic mobility. The equation is:
ζ = (μ * η) / (ε * ε₀)
Where:
- ζ = zeta potential (V)
- μ = electrophoretic mobility (m²/(V·s))
- η = fluid viscosity (Pa·s)
- ε = dielectric constant of the medium
- ε₀ = permittivity of free space (8.854 × 10⁻¹² F/m)
The calculator adjusts for temperature effects on viscosity and dielectric constant, ensuring accuracy for aqueous systems at 25°C or other conditions. Results are converted to millivolts for practical use.
User Guidelines
To use the Zeta Potential Calculator effectively, follow these steps:
- Enter Electrophoretic Mobility: Input the mobility in µm·cm/(V·s), typically obtained from electrophoresis experiments.
- Input Fluid Viscosity: Provide the viscosity of the medium (Pa·s). For water at 25°C, use 0.00089 Pa·s.
- Specify Dielectric Constant: Enter the dielectric constant of the fluid (e.g., 78.5 for water at 25°C).
- Provide Temperature: Input the temperature in °C to adjust for environmental conditions.
- Calculate: Click the “Calculate Zeta Potential” button to get the result in millivolts.
Ensure all inputs are positive and valid to avoid errors. The calculator includes input validation to enhance user experience.
