There is often a need of a certain average particle size for the ensemble of particles.

From the combined results Thomas's group estimated an average particle size of 100 for the copper metal aggregates.

Commercially available CSD has an average particle size of about 1 to 10 micrometres.

In addition, segregation of heterogeneous composites is avoided by granulating materials with different average particle sizes that are to be processed together.

It is mechanically pulverized, down to an average particle size of 8 microns, which makes it look like black talcum powder.

The throughput and also the operating costs of sensor-based sorters are lineary depending on the average particle size fed to the machine.

Through analysis of the resultant exponential autocorrelation function, average particle size can be calculated as well as a polydispersity index.

Also HPLC columns are made with smaller sorbent particles (2- 5 micrometer in average particle size).

In biological applications SAS is used to determine the structure of a particle in terms of average particle size and shape.

Larger surface area produces higher capacitance; thus high CV/g powders, which have a lower average particle size, are used for low voltage, high capacitance parts.

SAXS is used for the determination of the microscale or nanoscale structure of particle systems in terms of such parameters as averaged particle sizes, shapes, distribution, and surface-to-volume ratio.

Arkady yelled back information from Ann: the dust was extremely fine, average particle size about 2.5 microns; total column mass about 1/1000 of a grams per 100th cm, pretty evenly distributed from top to bottom of the column.
