The EXAFS study on Ru-Cu/Si02 of Sinfelt et al. [39] is one of the few examples where conclusions can be drawn on a qualitative base without the need to construct computer fits to the data. The following example illustrates EXAFS as a quantitative tool in a study of particle sizes. 

In 1952 W. J. Priest, in an important paper, laid out all of the basic qualitative features of the theory of homogeneous nucleation in emulsion polymerization as it is known today (12). This was based upon his studies of particle size distributions in vinyl acetate polymerization initiated by potassium persulfate (K2S20g) in the presence of varying amounts of different stabilizers and inhibitors at several temperatures. Priest proposed that (1) "polymerization in solution is the initial process" ... 

The conditions necessary for equality of particle size distribution were determined under ambient conditions. The nozzles used in the investigation can be classified as swirl-spray pressure nozzles. They accommodate a swirl insert which imparts a tangential velocity to the exiting fluid and results in a conical spray pattern. These nozzles were sufficiently different from conventional swirl nozzles (see Putnam et al., Ref. 6) to require an experimental study of particle size distribution.

During the past two decades, the isomerization of pentanes and hexanes has very often been used as a test reaction in the study of particle size or alloying effects. In these studies, the product distribution, and especially the percentage of cyclic molecules (cyclopentane or methylcyclopentane), have often been used for estimating the contribution of the cyclic mechanism. 

Shelf-life specifications of a suspension dosage form include redispersabihty upon storage. However, there is no official method to test this, and most manufacturers design their own methods, chiefly requiring some t q)e of subjective shaking. The stability of the suspensions is partly dependent on the particle size in suspension. This can be measured using techniques, such as laser diffraction or Malvern Mastersize (19). As the stabilized suspension is mostly in a flocculated form due to the electrolytes added to it, it may be necessary to apply sonification in the study of particle sizes.

A particle size analyzer determines the particle size distribution of powders either dry or dispersed in solvent by laser light scattering based on the Fraunhofer scattering theory. This type of equipment has an optical bench whose combined dynamic range is nominally 0.7-2000 pm. The instrument calculates mean diameters and distribution data. An interfaced computer generates sample histograms. This technique has been applied to the study of particle size and particle size distributions for polymer powders and polymer suspensions in a variety of solvents.
