This· Encyclopedia provides proved classical and instrumental methods, techniques, and procedures for the anal ysis and evaluation of raw materials, intermediates, and finished products. This volume presents chemical and physical characteristics for casein; caulking compounds; cellulose; cellu lose derivatives; cements, mortars, and concrete; centrifugal separation; ce ramics; cerium; cesium; chlorine; chlo rine compounds, inorganic; chlorocarbons, chlorophenols; chlorosulfonic acid; chocolate and cocoa products; choline and its derivatives; and chro mium. Also included in this volume are types of analysis available for the material itself and in mixtures, as well as commercial and analytical stan dards.

Unique research instruments priced f r o m only $2,175.00 • True Computer-Compatibility —A separate output direct from the chromatograph provides a full-range signal for integration. • Built-in Flow Controls —An exclusive, pressure-regulating flow controller is part of the instrument, not an option. Provides accuracy better than 0 . 1 % . • Research-Quality Oven —A full size ( 7 % χ 7% χ 8 % ") oven with a temperature range of 30 to 400°C and stability within 0.1 °C. • Wide-Range Electrometer —Low system noise, linear dynamic range of more than 200,000, and a time constant of 50 milliseconds produce clean signals which allow full use of electronic integrators and computers. The low cost of Series 407 Chromatographs was achieved by limiting their ver satility, not by c o m p r o m i s i n g quality. That makes them an ideal purchase for the research lab with an urgent need to add capacity, but a limited budget. 407 Series instruments can be used to implement techniques developed on more sophisticated chromatographs, without loss of data comparability.

Researchers in theoretical chemistry, chemical physics, spectroscopy, molec ular physics, and biology, as well as ad vanced undergraduates in quantum me chanics will find this book an invalu able reference. Through the use of this book, it is now possible to carry out any study where overlap integrals are required. The use of these tables pre cludes the need for a computer and re moves the traditional restriction of the types of atoms involved.
ANALYTICAL CHEMISTRY, VOL. 4 3 , NO. 6, MAY 1 9 7 1
This volume contains the text of the 48 contributed papers dealing with the chemistry of mixed ligands and outersphere complexes. These subjects were the only topics discussed at this symposium because of their importance. A Second Volume of the Proceedings will contain the text of the plenary lectures and also the full discussion material.
