Chapter 7: Displaying DataIf you enabled the “Calculate D10/D50/D90” feature in the Fixed Parameters(see page 4-3), you also see the D10, D50, D90, and Span values belowthe graph.Results Summary TableTo display the Results Summary table, right-click the RegularizationGraph and select Results Summary. (There is no Results Summary tableavailable when you are viewing the overlay graph for multiplemeasurements.)The Results Summary table gives a per peak breakdown of the size distribution.You can customize this table to include any or all of thefollowing columns:Column Name Description% Intensity The relative amount of light scattered by each population.% Mass The estimated relative amount of mass (concentration) of each peak or species.% Pd The polydispersity divided by the estimated hydrodynamic radius from the cumulantsfit of the autocorrelation function multiplied by 100.DiameterThe diameter of the particle in nm, determined by doubling the hydrodynamicradius estimate from the cumulants fit of the autocorrelation function.Diffusion Coefficient The translational diffusion coefficient for the peak.ItemThe column listing peak numbers. This column is labeled “Intensity Distribution”or “Mass Distribution” depending on the y-axis selection in the Control Panel.Mw-RThe weight-averaged molar mass estimated based upon the particle conformation,size, and density. Right-click on the units to change units.PdThe polydispersity, or width of the distribution, in nm determined using a Cumulantsanalysis.Pd IndexThe polydispersity index based on a Cumulants analysis. This is comparable tothe distribution width divided by the mean.RadiusThe mean value of the radius. Right-click on the units to change units.7-28 DYNAMICS User’s Guide (M1400 Rev. K)
