The Mass Spectrometer. In order to measure the characteristics of individual molecules, a mass spectrometer converts them to ions so that they can be moved about and manipulated by external electric and magnetic fields. The three essential functions of a mass spectrometer, and the associated components, are:
The mass spectrum shows that the peaks are in the ratio 10:1 and so there is 10 times as much Ne 20 as Ne 22 in the sample. From this data the relative atomic mass of neon can be calculated. simple diagram of a single beam mass spectrometer is required. The following stages of operation should be considered: vaporisation, ionisation, acceleration, deflection and detection. AIM 7: Simulations can be used to illustrate the operation of a mass spectrometer.
