• The identification and control of volatile organic compounds (VOCs) released by polymers during lamination in the photovoltaic (PV) industry is of considerable importance to establish and optimize processes in order to ensure a long term reliability of t ...
Several interlaboratory exercises were organised within the framework of European FP6 project NOR-MAN Among others. non-steroidal anti-inflammatory drugs were investigated in different aqueous samples in two sequential ring studies. The aim of both studies ...
In the present work, a polymer microfabricated microsprayer is characterised and tested for the mass spectrometric analysis of biomolecules, in particular in the context of protein mass spectrometry and proteomics. As the core of this work deals with analy ...
The coupling of the flow field flow fractionation to differential refractive index (DRI) and multi-angle laser light scattering detectors is a powerful tool for characterizing charged polysaccharides such as alginate. However, the correct interpretation of ...
The derivatization of cysteine-containing peptides with benzoquinone compounds is rapid, quantitative and specific in acidic media. The conversion of cysteines into hydrophobic benzoquinone-adducted residues in peptides is used here to alter the chromatogr ...
Current proteomic strategies depend strongly on the development of analytical methodologies and instrumentation. In parallel to the development of mass spectrometry (MS) - based proteomic workflows, microfluidic devices emerged in this field as a flexible ...
Hydrocarbon mass transfers to the atmosphere and water column drive the early weathering of oil spills and also control the chemical exposures of many coastal wildlife species. However, in the field, mass transfer rates of individual hydrocarbons to air an ...
Fourier transform ion cyclotron resonance mass spectrometry (FT-ICR MS) has been used to probe the interaction of the anticancer drug cisplatin with oligonucleotides. The binding kinetics, the nature of the adducts formed, and the location of the binding s ...
An electrospray microchip for mass spectrometry comprising an integrated passive mixer to carry out on-chip chemical derivatizations is described. The microchip fabricated using UV-photoablation is composed of two microchannels linked together by a liquid ...
Both ultrashort echo-time STEAM and MEGA-PRESS-edited spectroscopy were used to validate noninvasive quantification of vitamin C (ascorbate) in the developing rat brain, where changes in ascorbate concentration have been reported. Despite strong overlap wi ...
