*   Monoisotopic Mass
All the calculated masses displayed in the Formula Generator window are monoisotopic masses. The monoisotopic mass of an ion is the mass of the isotopic peak, which is composed of the most abundant isotopes of its elements. Because the system calculations support only single-charged ions (z=1), the calculated exact masses (not measured) in structure-based modules are equal to their m/z value.
