monton, Canada, June 1966. This symposium, consisting of the presentation of 28 papers was jointly sponsored by the ACS Analytical Division and AKALYTICAL CHEMISTRY.The majority of the papers have appeared in a number of issues of Separation Science. I n addition, a summary of the meeting was carried as a separate report in the January 1967 issue of ANALYTICAL CHEMISTRY, page 47 A. The papers are collected here in a single yolume.

^^
This book contains 27 papers covering various methods of sizing particles: manual counting (4papers) ; automatic counting ( 5 papers) ; sedimentation (6 papers) ; centrifugal sedimentation (4 papers) ; surface area measurements (4 papers); and two papers each on general subjects and on applications of particle size analysis. The papers were originally contributed by the authors (from Great Britain, U. s.,India, Japan, and the Netherlands) t o a Conference on Particle Size Analysis, organized by The 5’ociaty for Analytical Chemistry, and I-eld a t Loughborough University of Technology in September 1966. The discussions elicited a t the presentation of these papers were recorded and edited and. are included in this volume. Solvent Extraction Chemistry.

This book presents the Proceedings of the International Conference on Solvent Extraction Chemktry, held in Gothenburg, Auzar,t 27 to September 1, 1966. This conference was organized to emphasize the basic molecula ideas of solvent extraction. An effort was made also a t the meeting to bring the “applied” approach to the attention of theoretical chemists. The conference was attended by 190 active members from 25 countries. The papers given, collectcd in this book, are divided into sections uccording to the kind of reactions, molecular or physical, dominating the extraction process. These sections are: complexing in aqueous solutions by solvent extraction ; chelate extraction and adduct formation; neutral and acid phosphoryl compounds as extractants; alkyl ammonium salts and other ion pairs as extractants; structural effects and interfacial phenomena ; molten phases, Circle No. 188 on Readers’ Service Card

ANALYTICAL CHEMISTRY
Pyrometer shows that Tracerlab’s LTA-600 can ash samples thoroughly at temperatures well below 15OOC -low enough to leave all inorganic constituents unaltered. A cold plasma of atomic oxygen does the ashing, while our accessory pyrometer keeps you posted on the temperature. This low-temperature dry asher permits more accurate quantitative elemental and structural analyses of p l a n t a n d animal tissues, bones, coal, oil well cores, polymers, and radioactive materials. Prepares pure samples for atomic adsorption spectrophotometry, mass spectrometry, emission spectroscopy, X-ray diffraction, and electron microscopy.
