Flow perturbation gas chromatography refers to a family of techniques used to determine physicochemical constants for injected analytes or sorbent materials in which the carrier gas flow is either stopped for a short period of time or the direction of flow is reversed during the analysis. Equipment requirements are not unusual and such fundamental constants as diffusion coefficients, molecular diameters and critical volumes of gases, rate constants for chemical reactions, and activity coef-
Safety first Laboratory Safety and Health, an ACS Audio Course (4 audiocassettes, 4 h playing time, 168-page manual), by J. Kaufman, American Chemical Society, US$295.00 (U.S.A. + Canada)lUS$354.00 (rest of the world), additional manuals: us$20.00/ US$24.00
Edited by the Educational Division of the American Chemical Society, the course is aimed, as most ACS courses are, at advanced undergraduate students, graduate students, science teachers, and others who have no formal safety training. Management and supervisory personnel will find the material useful in developing a safety program. The course starts with the principles of laboratory safety: (1) Know the hazards before you
ficients, etc., are easily determined. For some applications better temperature, flow, and pressure control would be required than is normally found for commercially available analytical gas chromatographs. This book is written essentially for the physical chemist and most of the equations required for interpreting the chromatographic data are derived from first principles. Large sections of the text, in fact, contain more equations than text. The balance between theory and experimental data is reasonable except that I think greater attention should have been given to the influence of the experimental variables on the accuracy of the physical constants ultimately obtained. Flow perturbation methods should
start an experiment; (2) Answer three questions on the prudent practices, safety equipment, and protective facilities needed to minimize exposure to the anticipated hazards, on the worst accidents that can happen, and how to prepare oneself; (3) Make health and safety an integral and important part of the work. In the next section the course pays attention to the scope of the problem. The chances of meeting with a fatal accident in the laboratory, compared with, for, example, travelling by train, car or plane, or by climbing a mountain are discussed. Section C is devoted to questions of liability, the protection of people in the workplace, law suits against schools and colleges, and the duties of an employer or a teacher. The next section includes the types of hazards, the reduction of risks, chemical toxicity, preventing ingestion of toxic chemicals, preventing the inhalation of
be seen as just one method of using gas chromatography to obtain physicochemical information. Thus, the book is rather specialized and likely to appeal to a small audience. It is well written and contains no more than an acceptable number of typographic errors. The book is not for browsing or general reading and I doubt whether few analytical chemists would benefit from reading this text. As a comprehensive review of the perturbation techniques it serves well and should be purchased by physical chemists and others, interested in the measurement of fundamental constants by gas chromatography.

toxic fumes and avoiding skin contact with chemicals. In the book an extended list of dangerous chemicals, known and suspected carcinogenic, teratogenic and mutagenic compounds is given. The second part of this section is devoted to chemical flammability and explosivity, mechanical, electrical and radiation hazards. In the third part hazards of biological origin are discussed, and in the fourth and final part, physical hazards such as compressed gases, cryogenic liquids and noise. Section E discusses working with chemicals, their purchasing, storage, container size and labeling and the disposal of chemical waste. The next section deals with safety rules and recommended practices. The subjects covered include: working alone, personal hygiene, good laboratory practice, housekeeping, and eating, drinking and smoking in the laboratory. The supervisor should set a good example! Section G deals with protective
