Group Parameter Description
General Comment Enables you to enter a comment about the analysis
conditions. You can enter up to 40 characters.
Condition name Identifies the analysis condition. Use a unique, easily
recognizable name. You can use up to 40 characters.
Conversion Equation This is used to select the equation for calculating the
zeta potential from the mobility. You may select
Smoluchowski , Huckel , or Other . Generally,
Smoluchowski is used for aqueous samples and
Huckel is used for organic samples.
You must enter a coefficient when you select Other .
This coefficient is substituted for the “k” in the
following equation:
Z k


where
Z = Zeta potential


= Viscosity of the solution


= Dielectric constant of the solution
