In order to assist in the selection of the elements, the following information are displayed for each element

  • Nb iso: the number of isotopes
  • iso 5%: number of isotopes with over 5% abundance
  • % Δ-3: relative abundance of the isotope at a distance of -3Da compare to the more abundant isotope
  • % Δ-2: relative abundance of the isotope at a distance of -2Da compare to the more abundant isotope
  • % Δ-1: relative abundance of the isotope at a distance of -1Da compare to the more abundant isotope
  • % Δ1: relative abundance of the isotope at a distance of 1Da compare to the more abundant isotope
  • % Δ2: relative abundance of the isotope at a distance of 2Da compare to the more abundant isotope
  • % Δ3: relative abundance of the isotope at a distance of 3Da compare to the more abundant isotope
  • Min: Minimal number of this atom in the proposed molecular formula
  • Max: Maximal number of this atom in the proposed molecular formula
  • Many: Many of the selected elements may be present at the same time
