Abstract: This article presents information on mass spectrometers. Mass spectrometers precisely determine the masses of ionized atoms or molecules with extreme sensitivity. When some isotopes of a certain element decay radioactively, the isotopic intensity distribution reveals the age of the sample. Some of the isotopes exist only in very small quantities while others are abundantly available. For this reason it is very important to use a mass analyzer that provides for a rather small mass cross-contamination from one mass to the next. Laterally dispersive mass analyzers have proven to be effective and powerful tools exhibiting the lowest mass cross-contamination of all known mass analyzers.
