Common Adduct and Fragment Ions in Mass Spectrometry

WebOct 14, 2008 · Dalton is simply the alternate name for unified atomic mass unit. It is basically the molecular weight of a compound, independent of the concentration. It is also numerically equal to the molar mass in grams per mole. Flag Unregistered #3 06-23-2010, 12:51 PM Re: Dalton-->ppm Although relative atomic masses are defined for neutral atoms, they are measured (by mass spectrometry) for ions: hence, the measured values must be corrected for the mass of the electrons that were removed to form the ions, and also for the mass equivalent of the electron binding energy, Eb/muc . The total binding energy of the six electrons in a carbon-12 atom is 1030.1089 eV = 1.65… high school in 77459
