The aim of this work was to design a quick and reliable method for the evaluation and classification of wastewater streams into treatable and non-treatable effluents for reuse/recycling. Different chemometric methods were used for this purpose handling the enormous amount of data, and additionally to find any hidden information, which would increase our knowledge and improve the classification....

The potential utility of laser-induced breakdown spectroscopy (LIBS) as a means to detect biological contaminants on painted surfaces is investigated. Issues involving the use of LIBS for detection of biologicals are discussed. The apparatus assembled for this work is described, as is the manner in which samples of bare copper and painted substrates onto which thin layers of bacterial spores, p...

This chapter presents an introduction to robust statistics with applications of a chemometric nature. Following a description of the basic ideas and concepts behind robust statistics, including how robust estimators can be conceived, the chapter builds up to the construction (and use) of robust alternatives for some methods for multivariate analysis frequently used in chemometrics, such as prin...

The relative potential of various technologies for the confirmation of food authenticity and quality are discussed. Techniques that have found new applications in the field of quality assurance since 2001 are discussed in terms of their potential ease of application in an industrial setting. The use of specific techniques with chemometric analysis for the classification of food samples based on...

Chemometric tools were used to generate the modelling of solvent effects on the N-alkylation of an isocyanuric acid salt. The method proceeded from a central composite design applied on the Carlson solvent classification using principal components analysis. The selectivity of the reaction was studied from the production of different substituted isocyanuric derivatives. Response graphs were obta...

Historically, advances in the field of ion mobility spectrometry have been hindered by the variation in measured signals between instruments developed by different research laboratories or manufacturers. This has triggered the development and application of chemometric techniques able to reveal and analyze precious information content of ion mobility spectra. Recent advances in multidimensional...

A Chinese yellow wine classification method is proposed based on chemometric analysis of voltammogram of copper electrode. The main components in Chinese yellow wine are alcohol, amino acids and carbon hydrates. In strong alkaline solution copper electrode shows rich voltammetric responses to these components. Principal component analysis is employed to analyse voltammetric response of copper e...

Authenticity is an important food quality criterion. Rapid methods for confirming authenticity and detecting adulteration are widely demanded by food producers, processors, consumers and regulatory bodies. The objective of this work was to develop a model that would confirm the authenticity of Galician-labelled honeys as Galician-produced honeys. Nine metals were determined in 42 honey samples ...
