Web12 aug. 2024 · Metabolomics-based approaches are still receiving growing attention with regard to food authenticity testing. Such studies require enormous sample numbers with negligible experimental or analytical variations to obtain statistically reliable results. In this context, an extraction protocol in line with optimized ionization parameters was … Injecting ions into the Orbitrap and having them form stable trajectories is a quite complex task, with strict requirements on space/time distributions and kinetic energy. In order for them to obtain stable orbits, ions' kinetic energy must be well matched to the voltage on the center electrode. If the kinetic energy is … Meer weergeven Electrostatic ion traps were used as early as the 1920's, usually with two coaxial electrodes: a cylindrical outer electrode and a thin … Meer weergeven While the Kingdon trap provided a way to confine ions for extended periods of time, it did not provide an effective way of discriminating between the m/z values of the trapped … Meer weergeven Ions inside the Orbitrap are detected via image current. As the ions oscillate back and forth in the harmonic axial potential they induce current on the outer electrodes.
