Chemometrics is broadly defined as the application of mathematical and statistical methods to chemistry. Because the mathematical and statistical aspects of chemistry require measured values, analytical chemists have been at the forefront of the "chemometric revolution." Using the analysis of variance as a paradigm, I present an overview of chemometrics as it is practiced today. Receiving speci...
The genus Gentiana comprises approximately 400 species. Many species have a wide range of pharmacological activities and have been used therapeutically for thousands of years. To provide comprehensive guidance, utilization and quality control of Gentiana species, this review presents updated information concerning the recent application and progress of chemical analysis including phytochemical ...
Chemometrics is the application of statistical and mathematical methods to analytical data to permit maximum collection and extraction of useful information. It is a data-driven interdisciplinary science suitable for solving diverse applications. This review focuses mainly on various chemometric models used and their applications in the pharmaceutical sciences.
The power of comprehensive two-dimensional gas chromatography (GC×GC) for the study of complex mixtures has been indisputably proved in the past several decades. This review encompasses the whole of GC×GC-related data processing and summarizes relevant applications. We include theoretical introduction to some specific methods and studies to aid readers’ understanding of chemometrics strategies ...
Formaldehyde is a vastly used material in industry. Nowadays, it is proven that formaldehyde is toxic and carcinogenic. Thus providing a reliable method for its quantitative determination is very important. This study proposes a UV-Vis spectrophotometric based method for determination of formaldehyde. The method is based on reaction between the analyte and Fluoral P. Spectral changes during the...
Standards are central to the achievement and maintenance of accuracy in trace analysis. This fact is well-known and well-accepted in the international analytical chemical community, where "standards" are generally considered to be Standard Reference Materials (SRMs) or Certified Reference Materials (CRMs). The term, standards, however, is multivalued, as noted recently by a former Director of t...
and his main research activities concern chemometrics in all his aspects, the study of quantitative structure–activity relationships (QSAR), molecular descriptors, multicriteria decision making, and software development. President of the Italian Chemometric Society and member of the editorial advisory boards of relevant scientific reviews, he is full Professor of Chemometrics at the Department ...
Nowadays terahertz spectroscopy is a well-established technique and recent progresses in technology demonstrated that this new technique is useful for both fundamental research and industrial applications. Varieties of applications such as imaging, non destructive testing, quality control are about to be transferred to industry supported by permanent improvements from basic research. Since chem...
