Based on a symposium sponsored by the Division of Physical Chemistry of the American Chemical Society. An excellent representation of the present capabilities of laser methods. Since the direct application of lasers in combustion chemistry is particularly rel evant to energy production and pollution, this volume is both an important and timely contribution to the literature.
T h e model 600 TOC/ TOX: A supremely sensitive analyzer that's unafraid of dirt. Trihalomethanes: T h e M o d e l 600 T o t a l O r g a n i c C a r b o n Analyzer is precise but not prissy. You get precision of + 5 % at the 10 p p b level, and a packaged m o d u l e to per form the H P A ' s specified p r o c e d u r e for analysis of t r i h a l o m e t h a n e s . l Dirt: O n the other h a n d , you can routinely slug the system with a heavy TOC" sample and never c o m p r o m i s e its accuracy. So we make available an a m p u l e s a m p l i n g m o d u l e that lets you use the 600 like an ordinary TOC" — with e x t r a o r d i n a r y capabilities. T h e system will handle a n y t h i n g you put into the a m p u l e : soils, b r i n e s , s e d i m e n t s , crushed rocks, acids, caustics, sea water, you n a m e it. Automation: O p e r a t i o n is fast (5 m i n u t e s per sample), a u t o m a t i c and simple. T h e r e are separate cycles a n d p r i n t o u t s for purgeables and non-purgeables. l>erection is b y F I D . You d o n ' t have to " r i d e " the i n s t r u m e n t , or b o t h e r with sample pret r e a t m e n t s . M i c r o p r o c e s s o r logic handles multiple point calibration using least squares fit to a linear regression. Economics: If you need u l t r a p u r e capability, the model 600 should be your first choice. If you also need conventional, workhorse T O C , m e a s u r e m e n t s , it is the most cost-effective solution. O n e T O G that does everything well.

This broad-based forty-chapter volume describes how these laser probes, when combined with detailed computer mod els, can be used to provide pertinent chemical information for the design of clean and efficient means of fuel com bustion. CONTENTS The volume is divided into seven sections: overviews; laser-induced fluorescence and molecules; laser-induced fluorescence and atoms; spontaneous Raman scattering; coher ent Raman-scattering; modeling and kinetics; and other diagnostic techniques. Topics in clude laser probes of premixed laminar methane - air flames, the hydroxyl group in flames, saturation broadening, and nitric oxide detection in flames. The Nd:YAG laser mul tipass cell, CARS measurements in combus tion environments, Rayleigh scattering, and continuous-wave intracavity dye laser spec troscopy also are covered. 495 pages (1980) Clothbound $44.50 LC 80-17137 ISBN 0-8412-0570-1 Order from: SIS Dept.
