Mass Spectrometers

Mass Spectrometers use magnetic force to detect, identify and determine the concentrations of molecules based on their mass-to-charge ratio. All mass spectrometers must have an ion source, a mass analyzer, and an ion detector. To perform mass spectrometry, solid, liquid or gas test samples are loaded into the machine, and vaporized and ionized by the ion source. Sample molecules are given a charge that allows the mass spectrometer to speed the ions through electric and/or magnetic fields, which push the trajectory of individual ions according to their mass and charge. Mass analyzers may be used to separate ions in a sample for evaluation, or they can be used as a filtration system to deflect only particular ions in the direction of the detector.
