HIGH RESOLUTION MASS SPECTROMETRY IN LIPIDOMICS [PDF]
Mass Spectrometry Reviews, 2020 The boost of research output in lipidomics during the last decade is tightly linked to improved instrumentation in mass spectrometry. Associated with this trend is the shift from low resolution—toward high‐resolution lipidomics platforms. This review article summarizes the state of the art in the lipidomics field with a particular focus on the merits ...

Acyl-Lipid Δ6-Desaturase May Act as a First FAD in Cyanobacteria
Biomolecules, 2022 Fatty acid desaturases (FADs) play important roles in various metabolic and adaptive pathways in all living organisms. They represent a superfamily of oxygenases that introduce double bonds into the acyl chains of fatty acids (FAs).

A Quadrupole mass spectrometer for resolution of low mass isotopes [PDF]
Journal of the American Society for Mass Spectrometry, 2010 The qualitative and quantitative identification of low mass isotopes in the mass range 1-6 u poses certain difficulties when attempting to achieve the required resolution with an instrument suitable for deployment within a process environment. Certain adjacent species present in the process sample (HT and D(2)) require a resolution greater than 930 to ...

Charge resolution in the isochronous mass spectrometry and the mass of $$^{51}$$Co [PDF]
Nuclear Science and Techniques, 2021 Isochronous mass spectrometry (IMS) of heavyion storage rings is a powerful tool for the mass measurements of short-lived nuclei. In IMS experiments, masses are determined through precision measurements of the revolution times of the ions stored in the ring.

An atomic-resolution nanomechanical mass sensor [PDF]
Nature Nanotechnology, 2008 Mechanical resonators are widely used as inertial balances to detect small quantities of adsorbed mass through shifts in oscillation frequency[1]. Advances in lithography and materials synthesis have enabled the fabrication of nanoscale mechanical resonators[2, 3, 4, 5, 6], which have been operated as precision force[7], position[8, 9] and mass sensors[
