Regulatory Compliance Monitoring By Atomic Absorption Spectroscopy S.A. Katz and S.W. Jennies This book was prepared for the environmental scientist who uses this technique to determine heavy metal levels in air, water and wastewater, liquid and solid wastes, and biological tissues. It is directed to both the procedures preceding the absorbance measurements and the conditions under which atomic absorbance is measured. The procedures described in this manual reflect the current recommendations/requirements of the major regulatory agencies in North America. 1983. 288 pages. ISBN 0-89573-114-2. $37.50
Handbook of Particle Sampling and Analysis Methods C.H. Murphy This handbook presents the methods of particle sampling and analysis for those with limited experience in the field. It covers particle information, the properties of particles that can be investigated, terminology, units and the types of particle behavior that can exist, as well as sampling methods and instruments. 1984. 384 pages. ISBN 0-89573-116-9. Approx. $49.50

Preparation of Chlorophylls and Pheophytins by Isocratic Liquid Chromatography 251 Eight chlorophyll homologues are isolated by rapid, preparative-scale liquid chromatography. Purity of the pigments is determined by elemental analysis, liquid chromatography, and spectroscopic measurements. Tadashi Watanabe*, Akinori Hongu, and Kenichi Honda, Department of Synthetic Chemistry, Faculty of Engineering, University of Tokyo, Hongo, Bunkyo-ku, Tokyo 113, Japan, and Masataka Nakazato, Mitsuo Konno, and Sadao Saitoh, Research and Development Division, Nampo Pharmaceutical Co., Ltd., 1-6, Nihonbashi-honcho, Chuo-ku, Tokyo 103, Japan Anal. Chem., 56 (1984) Characterization of Reversed-Phase Liquid Chromatography Columns with Retention Indexes of Standards Based on an Alkyl Aryl Ketone Scale 256 Multivariant factor analysis is used to identify a set of standard compounds that can characterize reversed-phase liquid chromatography columns using retention indexes based on the alkyl aryl ketone scale. Roger M. Smith, Department of Chemistry, University of Technology, Loughborough, Leicestershire LE11 3TU, United Kingdom Anal. Chem. ,56(1984) Flow Injection Analysis with Enzyme Thermistor Detector for Automated Determination of /3-Lactams 263 /3-lactams are determined by flow injection analysis after reaction on a solid-bed enzyme reactor. Response is linear over the range 0.1-10.0 mg/mL, RSD is ±0.8%, and the detection limit is 1 0 - 6 g. Georg Decristoforo* and Bengt Danielsson, Biochemie Ges.m.b.H,, Research and Development Department, A-6250 Kundl, Austria Anal. Chem., 56 (1984) Determination of First-Order Reaction Rate Constants by Flow Injection Analysis 268 Theoretical and experimental considerations are discussed for the determination of first-order rate constants with flow injection analysis. The permanganate oxidation of benzaldehyde is used to illustrate pertinent points. Joseph T. Vanderslice*, Gary R. Beecher, and A. Gregory Rosenfeld, Nutrient Composition Laboratory, Beltsville Human Nutrition Research Center, United States Department of Agriculture, Beltsville, Md. 20705 Anal. Chem., 56 (1984) Determination of Dialkyllead, Trialkyllead, Tetraalkyllead, and Lead(ll) Compounds in Sediment and Biological Samples 271
After sample digestion with a tissue solubilizer, 10 organolead and Pb(II) species are isolated by chelation extraction and butylated for determination by gas chromatography with atomic absorption spectrometric detection. Y. K. Chau*, P.T.S. Wong, G. A. Bengert, and J. L. Dunn, National Water Research Institute and Great Lakes Fisheries Research Branch, Canada Centre for Inland Waters, Burlington, Ontario, Canada L7R 4A6 Anal. Chem., 56 ( 1984)
