Metabolomicsliquid chromatography-mass spectrometry
Bacterial cells harvested at peak enzyme activity were subjected to untargeted metabolomic profiling to evaluate metabolic changes during straw degradation compared to control (CK) groups. Samples were extracted using pre-chilled methanol–water (4:1, v/v) and analyzed on a UHPLC-Q Exactive HF-X syst...

MetabolomicsComparison of Full-Scan, Data-Dependent, and Data-Independent Acquisition Modes in Liquid Chromatography-Mass Spectrometry Based Untargeted Metabolomics
Full-scan, data-dependent acquisition (DDA), and data-independent acquisition (DIA) are the three common data acquisition modes in high resolution mass spectrometry-based untargeted metabolomics. It is an important yet underrated research topic on which acquisition mode is more suitable for a given ...

MetabolomicsImproving global feature detectabilities through scan range splitting for untargeted metabolomics by high-performance liquid chromatography-Orbitrap mass spectrometry
Untargeted metabolomics aims at obtaining quantitative information on the highest possible number of low-molecular biomolecules present in a biological sample. Rather small changes in mass spectrometric spectrum acquisition parameters may have a significant influence on the detectabilities of metabo...
