has part has_supplier bearer of has function Homo sapiens mass spectrometer A mass spectrometer is an instrument which is used to measure the mass to charge ratio of ions. All mass spectrometers consist of three basic parts: an ion source, a mass analyzer, and a detector system. The stages within the mass spectrometer are: 1. Production of ions from the sample 2. Separation of ions with different masses 3. Detection of the number of ions of each mass produced 4.Collection of data to generate the mass spectrum Frank Gibson LCQ Fleet Ion Trap MSn manufactured by thermo fisher scientific http://en.wikipedia.org/wiki/Mass_spectrometry mass spectrometer organization mass analyzer ion source ion detector measure function device setting measurement device ready for release
