Available in PDF, EPUB and Kindle. Book excerpt: Chromatography approaches are widely used in various life science applications. Since its invention by the Russian botanist Mikhail S. Tsvet in 1901, chromatography has increasingly developed into an invaluable laboratory tool for the separation and identification of chemical components. It outperforms older techniques (such as crystallization, solvent extraction, and distillation) by offering unequaled resolving power and the possibility of lowering detection limits to below nanogram levels. To further improve chromatographic methods, however, the use of chemometrics is advisable as an economical alternative to resolve any problematic situations in analysis. This book intends to provide the readers with an up-to-date application of chemometrics and data analysis to different types of chromatographic methods.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents an update on the basics, trends and achievements of chemometric methodology required to study the relation between the chemical structure of solutes and their retention in various chromatographic systems. The author critically analyzes hundreds of relevant papers published during the past two decades. In this period, chemometrics has evolved into an established research and practice area of interest to scientists ranging from chromatographers to environmental and medicinal chemists. Although emphasis is placed on the more recent findings, readers will also find the basic theories required to solve specific problems. It should prove advantageous for contemporary chemists and related scientists if they switch from thermodynamics - in practice often inappropriate - to a statistically based (and limited) chemometric approach.

Available in PDF, EPUB and Kindle. Book excerpt: The book reviews the basic concepts and highlights the most relevant advances and developments that have taken place in the field of comprehensive two dimensional gas chromatography (GC x GC) since its introduction in 1991. The several instrumental and technical approaches assayed and developed during these seventeen years and that have contributed to the development of this powerful separation technique and to its increasing application in many areas is explained and comprehensively illustrated through a number of chapters devoted these specific topics. More specialized aspects of the technique, including theoretical aspects, modelization of the chromatographic process, software developments, and alternative couplings is also covered. Finally, special attention is paid to data treatment, for both qualitative and quantitative analysis. This book will be a practical resource that will explain from basic to specialized concepts of GC x GC and will show the current state-of-the-art and discuss future trends of this technique. Outlines basic concepts and principles of GCxGC technique for non-specialists to apply the technique to their research Provides detailed descriptions of recent technical advances and serves as an instructional guide in latest applications in GCxGC Sets the scene for possible future development and alternative new applications of technique

Available in PDF, EPUB and Kindle. Book excerpt: In the field of Analytical Chemistry and, in particular, whenever a quali-quantitative analysis is required, until a few years ago, reference was made exclusively to instrumental methods (more or less hyphenated) which, once validated, were able to provide the answers to the questions present, even if only in a limited way to analytical targets. Nowadays, the landscape has become considerably complicated (natural adulterants, assessment of geographical origin, sophistication, need for non-destructive analysis, search for often unknown compounds), and new procedures for processing data have greatly increased the potential of analyses that are conducted (even routinely) in the laboratory. In this scenario, chemometrics is master, able to manage and process a huge amount of information based both on data relating only to the analytes of interest, but also by applying “general” procedures to process raw untargeted analysis data. It is within this strand of analysis that many of the works reported in this Special Issue fall. In the succession of works in this printed version, the criterion that guided us was to highlight how—starting exclusively from chromatographic techniques (HPLC and GC) with conventional detectors and moving to exclusively spectroscopic techniques (MS, FT-IR and Raman)—it is possible arrive at extremely powerful coupled techniques and procedures (HPLC and FT-IR) able to meet research needs. Finally, at the end of the printed volume, there are two reviews that surveying the state of the art regarding the assessment of authenticity through qualitative analyses and the application of chemometrics in the pharmaceutical field in the study of forced drug degradation products. From the succession of works (and, above all, from the various application fields) it can immediately be seen how the application of chemometrics and its procedures to both raw and processed data is a powerful means of obtaining robust, reproducible, and predictive information. In this manner, it is possible to create models able to explain and respond to the original problem in a much more detailed way. , and Honghe through Fourier transform mid infrared (FT-MIR) spectra combined with partial least squares discriminant analysis (PLS-DA), random forest (RF), and hierarchical cluster analysis (HCA) methods. Melucci and collaborators apply chemometric approaches to non-destructive analysis of ATR-FT-IR for the determination of biosilica content. This value was directly evaluated in sediment samples, without any chemical alteration, using attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy, and the quantification was performed by combining the multivariate standard addition method (MSAM) with the net analyte signal (NAS) procedure to solve the strong matrix effect of sediment samples. Still in the food and food supplements field, Anguebes-Franseschi and collaborators report an article where 10 chemometric models based on Raman spectroscopy were applied to predict the physicochemical properties of honey produced in the state of Campeche, Mexico.

Book excerpt: Ranging from elegantly simple to extremely complex, a wide variety of flavors and fragrances stimulate our senses. It is difficult to understand the myriad sensory interactions involved because of the sheer complexity of their chemical composition. The aim of this text is to describe the use of chemometric techniques for understanding these complex systems and to serve as a practical guide to the acquisition, organization and reduction of chemical and sensory data. It explains chemical, sensory and multivariate analysis tools and their application. Pertinent concepts are discussed in-depth and are sufficiently illustrated with enough original data in complementary tables and figures to provide the basis for the execution of complex studies. The book emphasizes techniques that have been proven to work rather than those that "should" work from a theoretical standpoint. The book focuses on the acquisition of quality data and the subsequent interpretation of data rather than numerical computations used in data analysis. Chemometrics: Chemical and Sensory Data is an excellent resource for students and newcomers to flavor and fragrance research, as well as for experienced workers and product development managers.
