WebThe lipid components in BALF were extracted by liquid–liquid extraction (methanol and methyl tert-butyl ether, and water). Ultra-high-performance liquid chromatography coupled to hybrid Quadrupole-Exactive Orbitrap mass spectrometry was used to analyze the extracted samples, which showed a broad scanning range of 215–1800 m/z. Web17 mei 2024 · The mass spectrometer can be operated in two modes, a) scan and b) selected ion monitoring (SIM). In the scan mode, it is set to detect all the ions from low m/z to high m/z values within a specified time period. This mode is used when analyzing unknown samples or when there is no available information about the ions present in a …
