a piece of equipment used by scientists to separate ions into groups to measure and compare their mass and electrical charge

an analytical instrument in which ions, produced from a sample, are separated by electric or magnetic fields according to their ratios of charge to mass. A record is produced (mass spectrum) of the types of ion present and their relative amounts
