A /sup 0/ light scattering photometer for analysis of single particles has been designed and developed. A fluid stream containing single particles intersects a focused laser beam at the primary focal point of an ellipsoidal reflector ring.

Get this from a library. Single particle analysis with a ̊light scattering photometer. [Marty Frank Bartholdi; Los Alamos Scientific Laboratory.; United States. Department of Energy.; National Cancer. The predecessors of today's single particle light scattering photometers are the ultramicroscopes of Siedentopf and Zsigmondy.

They used dark-field microscopy to prove the existence of discrete gold particles Cited by: 7. Single-Particle Sizing from Light Scattering by Spectral Decomposition Article (PDF Available) in Applied Optics 43(26) October with Reads How we measure 'reads'.

A differential light scattering photometer has been developed for rapid size analysis of single particles in flow. A fluid stream carrying individual particles in single file intersects a focused laser beam at the primary focal point of an annular strip of an ellipsoidal reflector situated in a scattering chamber.

Particle Size Analysis reviews the development of particle characterization over the past 25 years and also speculates on its future. Interest in the subject has increased enormously over the years and this book highlights the changes and advances made within the field.
