Mass Spectrometry is a scientific analytical technique used for determining the masses of atoms or molecules found in an unknown sample of gas, liquid, or solid. In a Mass Spectrometer, the unknown sample molecules is are passed through an ion source which converts it them into ions (if necessary, the sample is converted to a gas before it is passed through the ion source). The ions are then accelerated through a flight tube into an analyzer where the ionsthey are sorted according to their mass by an electromagnetic field. Once the ions are sorted, a detector determines the amount and type of each ion present by looking at specific characteristics such as mass and momentum (speed). The mass spectrum consists of a series of peaks of different mass and intensity from which the identity of the substance submitted for analysis can be determined. |
