In its simplest form, a mass spectrometer performs majorly three functions which are. it subjects the molecules to be analyzed to random bombardment by a stream of high energy electrons hence converting some of the molecules into ions. The ions are accelerated in an electric field by polarized plates that occur in a series. During this process, a large potential difference is created which ranges from 1 Kilovolt to 10 kilovolts which are applied across these accelerating plates and this produces a beam of rapidly traveling positive ions. Additionally, one or more focusing slits direct these ions into a uniform beam. Most of the sample molecules are usually not ionized at all but are drawn off continuously by vacuum pumps which are connected to the ionization chamber. Some of the molecules are converted to negative ions through the absorption of electrons. The negative ions are absorbed by the repelled plate and the small proportion of the positive ions formed. The repeller plate engages these destructive ions. A minor percentage of the positive ions which are made may have a charge larger than one. These are enhanced in a similar way as the individually charged positive ions.
