W. Lines, Coulter Electronics Limited, LutonParticle Size Analysis reviews the development of particle characterization over the past 25 years and also speculates on its future. Interest inthe subject has increased enormously over the years and this book highlights the changes and advances made within the field.The book is comprehensive in its coverage of particle size analysis and includes contributions on such characterization techniques asmicroscopy using fractal analysis, light diffraction, light scattering with the phase doppler technique, light observation, and photon correlationspectroscopy. A number of chapters address the interest in on-line in-stream particle size analysis and illustrate the progress being made inachieving this long sought after ideal of in-situ, in-process particle characterization.Applications to other technological fields are detailed bychapters covering biological systems and the pharmaceutical industry. The subject of surface area determination is considered with particularemphasis on the measurements on porosity of powders, the characterization and comparability of reference materials, and the need forstandards.Particle Size Analysis should provide stimulating reading for technologists, scientists, and engineers involved in particle characterization andpowder technology worldwide.Special Publication No. 102Hardcover xx+538pagesISBN 0 85186 487 2 (1992) Price €57.50ROYALSOCIETY OFCHEMISTRYTo Order, Please write to the:Royal Society uf Chemistry, Turpin Distribution Services Limited, Blackhorse Road, Letchworth, Herts SG6 1 HN, United Kingdom.or telephone (0462) 672555 quoting your credit card details.
