WebStep 1: Step 1: Identify the Molecular Ion The molecular ion represents the entire molecule in question, prior to any fragmentation. Each analyte molecule is given a charge of one, so the molecular ion m/z value represents the molecules total mass. WebAtomic mass is most conveniently described by the atomic mass unit, which is 1/12 of the mass of a carbon-12 atom. This means that each proton and each neutron contribute 1 amu to the mass of an atom, which makes it very easy to calculate. You can also use this to account for different isotopes.

WebOne AMU is the average of the proton rest mass and the neutron rest mass. This can be expressed as the following: 1 AMU = 1.67377 x 10 -27 kilograms = 1.67377 x 10 -24 grams Carbon-12 is considered a reference for all atomic mass calculations. Thus, the mass of any isotope of any element is expressed in terms of the 12 C standard of AMU. Examples
Ions can be non-chemically prepared using various ion sources, usually involving high voltage or temperature.
