WebNov 8, 2024 · The Effective Diameter was 131.5 nm and the PDI (polydispersity index) was 0.208. A PDI of 0.025 or less indicates a narrow size distribution. And the size above 100 nm also strongly suggests polydispersity. The intensity-, volume-, and number-weighted size distributions were calculated.

WebThe particle size distribution within the range is increased from 96.1% to 98.2%, which is modest, with virtually no difference overall in the volume distribution (Fig 8) The number distribution reduced from 48.5% to circa 2.5% by removing most particles 20 micron and under thereby eliminating the need for screening and reducing the blocking of ... WebD i = the diameter of the ith particle Σ = the summation of D ip or D iq, representing all particles in the sample Some of the more common representative diameters are: D‾10 = arithmetic or number mean D‾32 = volume/surface mean (also called the Sauter mean) D‾43 = the mean diameter over volume (also called the de Brouckere mean)
WebParticle size distribution can be represented in different ways with respect to the weighting of individual particles. The weighting mechanism will depend upon the measuring principle/technique being used. The most commonly used are number-weighted, volume-weighted and intensity weighted distributions (See Fig. 2). http://www.cif.iastate.edu/sites/default/files/uploads/Other_Inst/Particle%20Size/Particle%20Characterization%20Guide.pdf
