Flight mass spectrometer
WebAug 15, 2024 · Mass spectrometers always work with positive ions. Stage 2: Acceleration: The ions are accelerated so that they all have the same kinetic energy. Stage 3: Deflection: The ions are then deflected by a magnetic field according to their masses. The lighter … WebMass spectrometry is a powerful instrumental method of analysis. It can be used to: find the abundance and mass of each isotope in an element allowing us to determine its relative atomic mass find the relative molecular mass of substances made of molecules. A common form of mass spectrometry is time of flight (ToF) mass spectrometry.
