Time-of-Flight Mass Spectrometry - Agilent

The more parallel the ion beam, the higher the resolving power that can be achieved. After the ions have been shaped into a parallel beam, they pass through a pair of slits into the third and last vacuum stage. where the time-of-flight mass analysis takes place. Because the mass of each ion is assigned based on its flight time, the
