MetabolomicsOnline Headspace-Solid Phase Microextraction-Gas Chromatography-Mass Spectrometry-based untargeted volatile metabolomics for studying emerging complex biopesticides: A proof of concept
This work introduces a novel online Headspace-Solid Phase Microextraction-Gas Chromatography-Mass Spectrometry-based untargeted metabolomics approach, suggested as an alternative tool to study the environmental fate of volatile xenometabolites in emerging complex biopesticides, e.g. the Myrica gale ...

MetabolomicsMolecular networking coupled to high-resolution mass spectrometry fragmentation reveals a multitude of urinary antihypertensive drug metabolites
Mass spectrometry is the current technique of choice in studying drug metabolism. High-resolution mass spectrometry (HR-MS) in combination with fragment analysis (MS/MS) has the potential to contribute to rapid advances in this field. However, the data emerging from such fragmentation spectra pose c...

ProteomicsA combined gas phase separation strategy for ADP-ribosylated peptides
ADP-ribosylation (ADPr) is a posttranslational modification that is best studied using mass spectrometry. Method developments that are permissive to low inputs or baseline levels of protein ribosylation represent the next frontier in the field. High-field asymmetric waveform ion mobility spectrometr...

ProteomicsMass spectrometric and bio-computational analysis of multiply charged RNase S gas phase complexes obtained by electrospray ionization from varying in-solution equilibrium conditions
In this project we investigate the influence of a solvent's composition on the stability of desorbed and multiply charged RNase S ions by analyzing gas phase dissociation reactions triggered by collision induced dissociation (CID) of multiply charged complex ions. RNase S was dissolved in ESI-comp...
