M-w / M-n and X-w / X-n are both often erroneously called "**polydispersity** index", although they are not indices and the term "**polydispersity**" is not a defined quantity.

The following criteria were considered to be essential in the development of a light scattering method for Adenovector preparations: Analysis of vectors in their native state, determination of the mean particle size in the vector population, characterization of the homogeneity (**polydispersity** index and ...

value and record as the Mode or Peak value for each graph on the Work Form. For **Polydispersity** Index, divide the Weight average MW by the Number average MW.

Evaluating the derivative gives 1 X i=1 i 2 p i1 = 1+p (1 p) 3 (3.36) Multiplying by M 0 (1 p) 2 givesthefinal result: M W =M 0 1+p 1 p (3.37) Combining the results for M N andM W, the **polydispersity** index for the most probable distri-butionis M W M N =1+p (3.38) As the reaction nears completion, papproachesone and the **polydispersity** ...

The effect of **polydispersity** on the shape of the ﬂow curves was calculated. The simplicity of the model makes feasible its use in numerical simulations of complex geometries as encountered in
