How to analyze results of particle-size distribution measurement. The results of actual measurement of the particle sizes of a sample are as follows. In the laser diffraction method, "D10", "D50", "D90" (horizontal axis) and "volume percentage (Volume (%))" (vertical axis) indicate the following values.
Percentiles (d10, d50, d90) These values indicate the size below which 10%, 50%, or 90% of the particles fall. They are crucial for understanding the spread of particle sizes within a sample. Mean Particle Size. Calculated by averaging …
D50—median particle size; D10—10 percent of particles are smaller than this number; D90—90 percent of particles are smaller than this number; Narrower distribution curves will have these three D-values grouped more closely. A …
Alternative notations are x10/50/90 or D 0.1/0.5/0.9 The d50 value is also called "median" and it divides the particle size distribution into equal amounts of "smaller" and "larger" particles. Usually d10, d50 and d90 are reported for a particle size distribution.
The analyzed sample volume was varied between 0.05-2 mL so as to realize variation in the analyzed number of particles. The D10, D50, and D90* as a function of number of particles analyzed, are shown in Table 3 and Figure 1. Table 3. # particles sized vs. D10, D50 and D90
Step 3 – Inserting the Chart Go to the Insert tab in Excel.; In the Charts group, click on the Scatter (X, Y) or Bubble Chart dropdown.; Choose Scatter with Smooth Lines and Markers.; You'll see a blank chart after inserting it. To configure the chart, right-click anywhere on the chart area. Choose Select Data.; Click the Add button in the Select Data Source dialog box.
The length unit, D10 represents the 10% of particles in the powders are smaller than this size. Typically, the unit is μm. It can also be represented by a statistical symbols such as DV(0.1) or DV0.1. V means total volume. …
A D10, D50, D90 plot is a graph that displays the particle size distribution data, highlighting the D10, D50, and D90 values on the curve. What is the effective particle size D10? The effective particle size D10 represents the size below which 10% of particles are smaller in a particle size distribution.
Particle size distribution specifications based on the image analysis technique often include the mean, D10, D50, and D90 values. Care should be taken to avoid basing specifications on the number-based mean since this value may not track process changes such as milling or agglomeration (ref. 7).
D10, D50, D90, and the Span collectively provide a comprehensive overview of the particle size distribution, offering insights into the overall uniformity or diversity of particle sizes (Figure 3). Figure 3 Examples of NTA size distributions (RAW and FTLA) with associated span values as polydispersity indicator

The International Union of Pure and ... D10 D50 D90. 4 Questions to be considered when choosing a particle size analyzer include:
The most common approach for expressing laser diffraction results is to report the D10, D50, and D90 values based on a volume distribution. The span calculation is the most common format …
D10, D50, D90 & Span. • D50 & Span as primary BE parameters, and D10 & D90 as supportive parameters. ... the particle size distribution may not be monomodal (more than 1 peak). 4
Similarly D10 and D90 are 74 μm and 411 μm, indicating that 10% of particles are below 74 μm and 90% of particles are below 411 μm respectively. It should be noted that, for the individual size measurement, each of D10, …
For example, if the D90 is 844nm, this means that 90% of the sample has a size of 844nm or smaller. The definition for D50 or Dv (50), then, is then the size point below which 50% of the material is contained. Similarly, the …

Perzentile werden mit dem Buchstaben d, gefolgt von dem %-Wert bezeichnet. d10 = 83 µm, d50 = 330 µm und d90 = 1600 µm bedeutet also, dass 10 % der Probe kleiner als 83 µm sind, 50 % sind kleiner als 330 µm und 90 % sind kleiner als 1600 µm. Alternative Schreibweisen sind x10/50/90 oder D 0.1/0.5/0.9 Der d50-Wert heißt auch „Median".
