D1. 0, D5. 0, D9. DLS Yes not just diffraction. Spring 2014 X265'>Spring 2014 X265. Written by. Ulf Nobbmann. Size distributions are a description of the fact that not every component in the sample has the same size. There is a range of sizes present, as mathematically described by a distribution. There are different ways to represent this distribution in terms of Intensity How much light comes from the different componentsVolume or mass How much volume is present in the different components Number How many particles are present in the different componentsThis often causes confusion, and the intensity volume number issue is one of the most popular blogs. Intuitively most easiest to understand is the volume distribution we have so many cups, m. L or L of component A and so many of component B. If there is a range of components, i.

Dv9. 0 and signifies the point in the size distribution, up to and including which, 9. For example, if the D9. The definition for D5. Dv5. 0, then, is then the size point below which 5. D1. 0 or Dv1. 0 is that size below which 1. Lao Font Software here. This description has long been used in size distribution measurements by laser diffraction. An additional parameter to show the width of the size distribution is the span. The span of a volume based size distribution is defined as Span D9. D1. 0D5. 0 and gives an indication of how far the 1. Can DLS be used to obtain D1. D5. 0D9. 0 and span Yes, the standard Zetasizer software  can display volume particle size distributions and there is a feature to customize the record view as well as reports to include these additional parameters however, do read the cautionary note below.

Caution what do you want to do with these valuesWhile it is possible to calculate these parameters for DLS, please keep in mind that they are derived from a volume distribution which is derived from an intensity distribution, which is itself obtained from a correlation function. Due to the inherent errors that may be part of this deconvolution, we strongly advise against using any Dv parameters obtained from DLS for quantitative control. If this is the objective of your interest, then laser diffraction is the more robust method as well as well documented with existing ISO and ASTM standards for this purpose. Previously.
