Low density polyethylene (LDPE) and high (HDPE) are the principal plastics present in solid plastic waste found out as main components of microplastics marine terrestrial environments. Currently, efforts have been made to develop new effective methods ensure identification separation waste, ensuring necessary purity obtain quality economically competitive recycled products. In this contribution...

In viscose production, it is important to monitor three process parameters as part of the spin-bath in order to assure a high quality of the final product: the concentrations of H2SO4, Na2SO4 and ZnSO4. During on-line production these process parameters usually show a quite high dynamics depending on the fibre type that is produced. Thus, conventional chemometric models, kept fixed during the w...

In general, applications of metabonomics using biofluid NMR spectroscopic analysis for probing abnormal biochemical profiles in disease or due to toxicity have all relied on the use of chemometric techniques for sample classification. However, the well-known variability of some chemical shifts in 1H NMR spectra of biofluids due to environmental differences such as pH variation, when coupled wit...

Rapid techniques for virus identification are more relevant today than ever. Conventional virus detection and identification strategies generally rest upon various microbiological methods and genomic approaches, which are not suited for the analysis of single virus particles. In contrast, the highly sensitive spectroscopic technique tip-enhanced Raman spectroscopy (TERS) allows the characterisa...

The adsorption of the proton-pump inhibitor omeprazole was investigated using RP-LC with chemometric models combined with adsorption isotherm modelling to study the effect of pH and type of organic modifier (i.e., acetonitrile or methanol). The chemometric approach revealed that omeprazole was tailing with methanol and fronting with acetonitrile along with increased fronting at higher pH. The i...
