    CriticalMicelleConcentration

    The concentration of surfactants above which micelles form and all additional surfactants added to the system go to micelles. This is the concentration where increasing the concentration of the sample stops decreasing the surface tension.
    Format: Single
    Class: VariableUnit
    Programmatic Pattern: Gram Hold[GreaterP[0 Molar] | GreaterP[0 -----] | RangeP[0 Percent, 100 Percent]] Liter

    ApparentPartitioning Coefficient

    An apparent partitioning coefficient used to quantify partitioning the air-water interface. This is the inverse of the concentration where increasing the concentration of the sample starts decreasing the surface tension.
    Format: Single
    Class: VariableUnit
    Programmatic Pattern: 0 Liter 0 Hold[GreaterP[-----] | GreaterP[0 -----] | GreaterP[-------]] Molar Gram Percent

    SurfaceExcessConcentration

    The amount of surfactant adsorbed at the air water interface per surface area. This is calculated by taking the negative of the slope of the concentration dependent region of a surface tension vs. log of concentration graph divided by the temperature the measurement was taken at and the ideal gas constant.
    Format: Single
    Class: Real
    Unit: 1 mole per meter squared
    Programmatic Pattern: Mole Hold[GreaterP[0 ------]] 2 Meter

    CrossSectionalArea

    The area of the surfactant molecule at the surface. This is calculated by taking the inverse of the SurfaceExcessConcentration and the Avogadro constant.
    Format: Single
    Class: Real
    Unit: 1 meter squared
    Programmatic Pattern: 2 Hold[GreaterP[0 Meter ]]

    MaxSurfacePressure

    The largest surface pressure of the dilutions. This is also the difference between the surface tension of the diluent and the surface tension of the most concentrated dilution.
    Format: Single
    Class: Real
    Unit: 1 millinewton per meter
    Programmatic Pattern: Newton Hold[GreaterEqualP[-100 Milli ------]] Meter
