WebJul 24, 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 they are, the more they are deflected. WebThe mass spectrometer is fitted with a special device, a sniffer probe, that allows it to sample air (and tracer gas when confronted with a leak) at atmospheric pressure and to bring it into the mass spectrometer. This mode of operation is frequently used to locate a leak that has been detected by other methods, in order to allow for parts repair. green and black vintage carpet
