The use of molecular tools for the detection and identification of invertebrate species enables the development of more easily standardisable inventories of biological elements for water quality assessments, as it circumvents human-based bias and errors in species identifications. Current Ecological …

Siliconen, meestal dimethicone en dimethiconol, worden vaak gebruikt als conditioneringsmiddelen in shampooformuleringen. Ze zijn al effectief op zeer lage niveaus. Siliconen bezitten een reeks unieke eigenschappen zoals smerend vermogen, lage intermoleculaire krachten, onoplosbaarheid in het water …

Rijkswaterstaat draagt de zorg voor het monitoren van de hoofdwatersystemen in Nederland. Hiervoor worden schadelijke stoffen gemonitord, waaronder glyfosaat, AMPA, glufosinaat en MPPA. Deze stoffen worden gemeten met IC-HESI-MS/MS, na een voorbehandeling met SPE-kolommen om storende stoffen te verwijderen. …

In collaboration with Eindhoven University of Technology, the goal is to synthesize water-soluble supramolecular fiber components (hydrogels) based on the BTA for mimicking the ECM. Is these BTA components the tetraethylene glycol units would be replaced by mono- or disaccharides, e.g. glucose or cellobiose. …

Corals harbor complex and diverse microbial communities that strongly impact host ftness and resistance to diseases, but these microbes themselves can be infuenced by stresses, like those caused by the presence of macroscopic symbionts. In addition to directly infuencing the host, symbionts may transmit …

Purpose. Staphylococcus haemolyticus has emerged as a highly antimicrobial-resistant healthcare-associated pathogen, in particular for patients admitted to neonatal intensive care. The objective of this study was to study the nature of SCCmec types among MDR-SH strains isolated from paediatric patients. Methodology. …

This paper describes the development of one solid phase extraction method for a wide group of pharmaceutical and industrial compounds in wastewater that is analyzed with two LC-MS/MS methods.

Bij een incident kunnen stoffen vrijkomen die mens, milieu en dier mogelijk in gevaar kunnen brengen. Hiervoor is het noodzakelijk om snel informatie te verkrijgen van de vrijgekomen stoffen. De informatie kan worden gehaald uit analyseresultaten van de op de locatie verkregen monsters. Hedendaags wordt …

For research to the composition of oxylipids in human plasma and tissue it was necessary to have an analytical method that can measure these lipids on very low concentrations. In this bachelor thesis the development of a LC-MS method will be discussed.
