A mass spectrometer determines the mass of a molecule by measuring the mass-to-charge ratio (m/z) of its ion.
WebWhen the vaporized organic sample passes into the ionization chamber of a mass spectrometer, it is bombarded by a stream of electrons. These electrons have a high enough energy to knock an electron off an organic molecule to form a positive ion. Webnucleon mass actually mean, and how differences should be interpreted (Cristoni and Bernardi 2004, Sleno 2012, Sugimoto et al 2012, Barbara et al 2011). This perspective focuses on the concept of ‘exact mass’ which is the fundamental physics principle for high-resolution mass spectrometry. Certainly most
