The IUPAC definition of resolution in mass spectrometry expresses this value as m/Δm, where m is the mass of the ion of interest and Δm is the peak width (peak width definition) or the spacing between two equal intensity peaks with a valley between them no more than 10 % of their height (10 % valley definition) [http://dx.doi.org/10.1351/goldbook]. Resolving power in mass spectrometry is defined as the ability of an instrument or measurement procedure to distinguish between two peaks at m/z values differing by a small amount and expressed as the peak width in mass units [http://dx.doi.org/10.1351/goldbook]. Mass resolving power is defined separately as m/?

Alternative definitions for resolution and resolving power in mass spectrometry have been proposed [http://mass-spec.lsu.edu/msterms/index.php/Mass_Spec_Desk_Reference][http://goo.gl/4kP05]. It has been suggested that resolution be given by Δm and resolving power by m/Δm; however, these definitions are not widely used.
