The key measurements that we use in setting up the Quadro Mills is to cite three values—the D10 D50 and D90 as shown in Figure 2 The D50 the median is defined as the particle size where half the population lies below this value Similarly 90 percent of the population lies below the D90 point and 10 percent of the population lies below the D10
Similarly d10 = x10 = the 10th percentile = the diameter of a sphere at which 10% of the particles in the sample are smaller; on a volume basis = D v and so on Other details in the notation can change as well D n = the diameter of a sphere at which 10% of the particles in the samples are smaller on a number basis The n indicates the basis Sieve Sizes Length Units

Particle size results should be reproducible and repeatable According to the USP test 429 Light diffraction measurement of particle size the predicted repeatability for three measurements should agree within a coefficient of variation COV of less than 15% at the D10 and D90 and less than 10% at the D50 The COV is defined as
Particle size influences many properties of particulate materials and is a valuable indicator of quality and performance This is true for powders suspensions emulsions and aerosols The size and shape of powders influences flow and compaction properties Larger more spherical particles will typically flow more easily than smaller or high aspect ratio particles Smaller particles dissolve

Data at three points d10 d50 and d90 on the distributions were tabulated and evaluated for all 58 methods validated The median volume diameter d50 was found to be adequate for method validation The approach rapidly generated valid reproducible particle size distribution analysis methodology
The results of the analysis showed that the largest particle size of d50 was mm at station 14 and the biggest particle size of d90 of mm was also obtained at station 14 The results attained were due to the dynamics of the ocean currents and the flow of the river interacting at station 14 This could happen because during the high tide the dominant flow is coming from the sea it
