Book Synopsis Advances in Chemical Analysis Procedures (Part II) by : Marcello Locatelli
Download or read book Advances in Chemical Analysis Procedures (Part II) written by Marcello Locatelli and published by MDPI. This book was released on 2021-01-20 with total page 224 pages. 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.

Download or read book Chemometrics written by David R. Burgard and published by CRC Press. This book was released on 2018-01-31 with total page 452 pages. Available in PDF, EPUB and Kindle. 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.

Book Synopsis Chemometrics and Chromatography by : Siong Fong Sim
Download or read book Chemometrics and Chromatography written by Siong Fong Sim and published by . This book was released on 2011 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chromatography has undergone rapid and unprecedented growth over the past few decades. This has had a great influence on the rate at which analytical data is acquired. The advances in chromatography have created datasets that are not amendable to traditional manual approaches, not merely because of the size but also because of the increasing complexity. Chemometrics is introduced to enhance the analysis of chromatographic data. In this thesis, chemometric approaches are applied for analysis of coupled chromatographic data from various areas: microbial study, fruit spoilage are archaeological study. A novel automated peak detection and matching algorithm is reported for the analysis of Gas Chromatography-Differential Mobility Spectrometer (GC-DMS) chromatograms.

Book Synopsis A Chemometrics Guide for Chromatographers by : Gabriel Vivo-Truyols
Download or read book A Chemometrics Guide for Chromatographers written by Gabriel Vivo-Truyols and published by Elsevier. This book was released on 2023-10-01 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Chemometrics Guide for Chromatographers, Volume 33 in the Data Handling in Science and Technology series, helps bring chemometrics and statistics to the chromatographic field, with the aim of making the statistical tools understandable and useful for this community. There are excellent textbooks about chemometrics and chromatography available on the market, but none are devoted solely to bringing both fields together in a simple language. The nature of the data arising from chromatography deserves special attention (e.g., data alignment, hyphenation or two-dimensional chromatography) and is thoroughly covered in this comprehensive resource, along with other specialized chapters. Over recent decades, chemometricians have been busy developing algorithms and smart statistical techniques to (i) Optimize analytical instruments and (ii) Extract the maximum information out of the data generated by the instruments. It is no longer possible for separation scientists and chemometricians to work in isolation, as both spheres of knowledge must go hand-in-hand. Bridges the gap between analytical chemistry and chemometrics Provides an overview of the data that arises from chromatography (i.e., data alignment, hyphenation or two-dimensional chromatography) Looks at how chemometrics can enhance chromatographic techniques

Book Synopsis Chemometrics in Food Chemistry by : Anna de Juan
Download or read book Chemometrics in Food Chemistry written by Anna de Juan and published by Elsevier Inc. Chapters. This book was released on 2013-06-08 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: The term multivariate curve resolution (MCR) designates a family of methods devoted to solving the mixture analysis problem in multicomponent samples. MCR provides the qualitative and quantitative contribution (profile) of each of the compounds in a sample from the sole information of the raw experimental data acquired. Food analysis is about knowing the qualitative and quantitative composition of foodstuffs and, hence, MCR fits very well in this scenario. Typical problems related to food analysis that can be solved by MCR are the identification and analytical determination of target compounds in the presence of unknown interferences/compounds, obtaining food fingerprint information to be used for authentication, adulteration or other purposes, and the interpretation of food processes. All these situations can be solved by handling measurements as simple as a data table with one spectrum (response) per sample or as complex as flexible multiset structures formed by several data tables (e.g. excitation/emission spectra, hyphenated separation techniques: high-performance liquid chromatography with diode array detection, liquid chromatography or gas chromatography–mass spectrometry, etc.), each of them related to a sample or to a particular food condition.
