Chemometrics & Informatics @ spectroscopyNOW

This channel covers research and development into all aspects of chemometric and informatic techniques used in chemical data analysis, including quality control and batch monitoring as well as experimental design and signal processing using PCA, MVA, PARAFAC, PLS, and LIMS.

Monthly Highlight

Last Month's Most Accessed Feature: Biodiesel analysis: Biofuel blend by NMR spectroscopy

A new quantitative method of analysing the biodiesel in a diesel-biodiesel blend using proton nuclear magnetic resonance spectroscopy has been developed by researchers in Brazil. The resulting spectra are subjected to a univariate calibration in which the integrals of the spectra are considered. Statistical comparison with infrared (IR) spectra corroborate the findings.

So-called ‘herbal’ slimming aids are often adulterated with banned slimming drugs or other chemicals, to increase their effectiveness. Researchers at the Scientific Institute of Public Health in Brussels and the University of Antwerp examined several different samples of such products by UHPLC, classifying them using various chemometric methods, such as hierarchical cluster analysis (HCA), Classification and Regression Tree (CART), and partial least squares discriminant analysis (PLS-DA).

Multi-spectral imaging at 405–970 nm coupled with back-propagation neural networks has been used successfully for the detection of dicyandiamde in infant formula powder.

An analysis of mass spectrometric data reveals the existence of three toxicologically important methylated phenylarsenical metabolites in chicken liver from fowl given feed containing the additive 3-nitro-4-hydroxyphenylarsonic acid (ROX). The additive was banned in the European Union in 1999 and in the USA in 2013, but still widely used elsewhere.
