Bioanalytical Separations is volume 4 of the multi-volume series, "Handbook of Analytical Separations," providing reviews of analytical separation methods and techniques used for the determination of analytes across a whole range of applications. The theme for this volume is bioanalysis, in this case specifically meaning the analysis of drugs and their metabolites in biological fluids.
- Discusses new developments in instrumentation and methods of analyzing drugs and their metabolites in biological fluids
- Provides guidance to the different methods, their relative value to the user, and the advantages and pitfalls of their use
- Future trends are identified, in terms of the potential impact of new technologies

vi as did non-appreciation that % values for bought-in solutions (notably ammonia) may be on a weight basis, not made evident by the manufacturer. Notwithstanding the shortcomings or lateness of some texts, authors are thanked for compiling them amidst other pressures. Elsevier and the American Chemical Society are also thanked, for Figures now reproduced with source acknowledgement. This Editor has generally respected authors' phrasing, whilst shuddering when the term 'incubate' is encountered in a 0 Degrees context. He remains a 'diehard' in certain respects, notably in favouring 'M' rather than 'mol/I', and a wt./ml basis for drug concentrations in test samples; he regards 'mmol/l' as a fatuous fashion. Concerning infelicitous abbreviations, a distinction is made between electron capture (detector context; 'ECD') and electrochemical ('EC', never 'ECD'); the hallowed GC term 'FID' means free induction decay to NMR practi tione:ts, who may pardon the term 'Fid' as introduced editorially. The convention for ,0C' throughout the book is '0'. Undefined but well-known abbreviations include GC, HPLC and TLC. MS (mass spectrometry), NPD (nitrogen-phosphorus detector), tr (retention time) and RIA (radioimmunoassay) are usually defined in the article concerned, as are the HPLC modes NP (normal-/straight phase) and RP (reversed-phase; C-lS and ODS are synonymous), and i.s.

This volume explores the different approaches and techniques used by researchers to study the recent challenges and developments in metabolic profiling. This book is divided into IV parts. Part I contains chapters that highlight basic concepts, such as experimental design, data treatment, metabolite identification, and harmonization. Part II describes experimental protocols for both targeted and untargeted metabolomics covering the basic analytical technologies: LC-MS, GC-MS, NMR and CE-MS. In addition the protocols describe methods for the study of tissues, feces, blood and other types of biological samples as well as the application of chemical derivatization for GC-MS. Parts III and IV present the use of metabolomics in the study of food, plants and the life sciences, with examples from the quest for the discovery of disease biomarkers, physical exercise omics and metabolic profiling of food, fruit and wine. Written in the highly successful Methods in Molecular Biology series format, chapters include introductions to their respective topics, lists of the necessary materials and reagents, step-by-step, readily reproducible laboratory protocols, and tips on troubleshooting and avoiding known pitfalls. Authoritative and thorough, Metabolic Profiling: Methods and Protocols is a valuable resource for researchers who are interested in expanding their knowledge of this rapidly developing field.

K. pharmaceutical companies - Beechams, Glaxo, ICI and Smith, Kline & French. Moreover, some speakers came without full financial coverage.

Jim Leppard and Joan Reid are thanked for Index drafting. As mentioned in the text, some Figs. have already appeared in journals, whose publishers (e.g. Elsevier, Dekker, Preston) are thanked: sources include Journal of Chroma- tography, Journal of Liquid Chromatography and Journal of Chromatographic Science, also (art. #E-S) a Wiley book edited by M. Trimble. Abbreviations.- In connection with HPLC ('LC' is a pet aver- sion) this Editor has often deplored the upstart use of 'ECD'-a term hallowed by its GC usage as in art. #F -2 later in the book. To connote 'electrochemical' the term 'EC' is now used, but 'ECD' is reserved for the electron-capture detector. Other abbreviations which, although well known, are generally defined in each article concerned include NP, normal-phase [HPLC); RP, reverse(d)-phase; i.s., internal standard; MS, mass spectrometry (EI, electron-impact; CI, chemic,al-ionization); RIA, radioimmunoassay; UV, ultraviolet (usually absorbance).
