## Zimm plot

https://doi.org/10.1351/goldbook.Z06748
A diagrammatic representation of data on @S05487@ from large particles, corresponding to the equation: $\frac{K_{c}}{\Delta R (\theta)} = \frac{1}{\bar{M}_{\text{w}}\ P (\theta)}+2\ A_{2}\ c+\text{ ... }$ and used for the simultaneous evaluation of the mass average molar mass, $$\bar{M}_{\text{w}}$$, the second @V06625@ of the @C01032@, $$A_{2}$$, and (usually) the z-average @R05121@, $$< s^{2} > _{\text{z}}^{\frac{1}{2}}$$; $$c$$ is the mass concentration of the solute, $$\Delta R(\theta)$$ the excess @R05159@, and $$P (\theta )$$ the @P04429@ that comprises (usually) the z-average @R05121@. $$K$$ depends on the solute, the temperature and the type of radiation employed. Several modifications of the Zimm plot are in frequent use; the most common one uses the excess @S05487@ instead of the @E02236@.
