Journal of Automatic Chemistry
This book, in the fine tradition of Ellis Horwood publications, has been updated considerably and now fully fits the needs of the analytical market. The pressure on all laboratories to achieve national and international accreditation and to achieve good laboratory practice has placed a demand on quality-control procedures. This book, written from practical experience, allows any laboratory, with just the addition of an IBM PC, to introduce good quality-control procedures. The necessary software
... is available from the publisher on disk. The first edition was extremely well received; to meet new demands in legislation a chapter has been added to the second edition to deal with external quality-control schemes. More attention has also been given to identifying the trends in qualitycontrol data. Specifically, the autoregressive moving average model to identify trends is introduced in this text. The book provides the user with all that is required and identifies possible errors introduced by computational errors in the PC. The user does not have to be frightened by statistical approaches and can adequately deal with the quality assurance problems of analytical chemistry without passing them on to an external statistician. The book includes 70 references and identifies other areas of suitable reading. It is attractively produced with the distinctive cover styles of the Ellis Horwood publishing house. An extremely valuable addition to the analytical chemistry laboratory and good value at 29.95. On-Line Coupled LC-LG This manual, which is part of a series on chromatographic methods, concentrates on the techniques for transferring the usually large volumes of LC eluent to GC. Selective solvent evaporation at a sufficiently high rate is at the heart of the transfer. The LC-GC interfaces required for the different transfer techniques are described in detail, followed by a discussion of applications in order to show the practical implications. The book is based on an inductive approach. After a presentation of partial transfer from LC to GC (Section 2), considered to be of limited interest, Section 3 describes the basic concepts that it should be simple to rebuild the systems. Section 6, on LC techniques suitable for LC-GC, shows how much is left to be done in this field. Sections 7 and 9 describe the presently used transfer techniques (retention gap techniques, concurrent eluent evaporation), while Sections 8 and 10 discuss applications involving the corresponding transfer methodsthey should illustrate theory through practice. Section 11 gives some comments on the idea of using liquefied gases on supercritical fluids for sample preparation instead of ordinary LC eluents. As coupled techniques receive more attention a basic reference text like this forms an ideal foundation for the researcher.
