rected towards the best available proven methodologies. The chapter on formulated products effectively updates most of the standard texts and reviews active areas of development such as electrochemical techniques, the separation sciences and infrared spectroscopy. An important conclusion is that new spectroscopic, multicomponent methods are developing rapidly and will become cost effective. Trace component analysis in surfactants is reviewed in chapter 3. This chapter describes the standard approaches to analysis and their current limits of application. The niche market of amphoteric surfactants is addressed in the fourth chapter. The author describes the principal types of amphoteric surfactants at some length and details the standard analytical requirements. On-line techniques for surfactant analysis are addressed in the following chapter. This timely review makes interesting reading by addressing a wide field of new methods and technical advances and providing a practical and pragmatic commentary , about their potential future applications as robust systems. The growing area of analysis of test liquors and environmental samples is well covered by the final chapter. Much of the discussion in this section deliberates upon the difficulties placed before the analyst; in particular those derived from the matrices, sampling, detectability and analyte losses attributable to the methods.
present book, based on a course organized by the Thermal Analysis Consultancy Service in Leeds, 12-13th September 1991, was written by twelve specialists in thermal analysis, some of them with world-wide reputations. Thermal analysis deals with differential thermal analysis (DTA), differential scanning calorimetry (DSC), thermogravimetry (TG), simultaneous TG-DTA/DSC, thermomechanical analysis and dynamic mechanical analysis as the most important methods, as well as thermomicroscopy, high temperature x-ray diffraction, and evolved gas analysis. Besides these methods there are applications in various fields, such as of minerals, pharmaceuticals, polymers, materials science and quality assurance. The book also offers a short introduction for beginners as well as for the experienced scientist and engineer. The added list of sources of information in thermal analysis and of addresses of companies supplying thermal analysis equipment in the U.K. could be helpful. In this book I have noted only a few mistakes, e.g., p. 189, Fig. 2, Form 1 and 2 are incorrectly interchanged. Some double fractions (such as the one on p. 571, are difficult to read and understand. It is perhaps unfortunate in this age of desktop computers that the book has no uniform style as a result of the decision to employ camera ready manuscripts. As a whole the book can be recommended.

Thermal analysis has been among the most rapidly developing methods in recent years as a result of the increase of applications. In comparison with other analytical techniques such as chromatography or spectroscopy to date there are only relatively few books on thermal analysis. The

The first edition (1987) was the first full length text in this area aimed primarily at chemometricians. An appreciation of experimental design is important for effective research, but conceptual advances are often best presented in textbook and tutorial form rather than as original research papers.
