| The IUPAC definition of resolution in mass spectrometry expresses this value as m/?m, where m is the mass of the ion of interest and ?m 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/?m in a manner similar to that given above for mass resolution [http://dx.doi.org/10.1351/goldbook]. These definitions of mass resolving power and resolving power in mass spectrometry are contradictory, the former is expressed as a dimensionless ratio and the latter as a mass. The definitions for resolution in mass spectrometry and resolving power in mass spectrometry come from Todds 1991 recommendations [http://dx.doi.org/10.1351/pac199163101541], and the definition for mass resolving power comes from Beynons 1978 recommendations [J. Beynon. Pure Appl. Chem. 50, 65 (1978)]. Beynons work contains no definition for mass resolution.
| |
| | |
| 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://dx.doi.org/10.1002/(SICI)1098-2787(1998)17:1<1::AID-MAS1>3.0.CO;2-K]. It has been suggested that resolution be given by ?m and resolving power by m/?m; however, these definitions are not widely used.
| |
| | |
| The majority of the mass spectrometry community uses resolution as defined by IUPAC. The term resolving power is not widely used as a synonym for resolution. In this document, the IUPAC defini- tion of resolution in mass spectrometry remains in place. The definition of resolving power has been adapted from the current IUPAC definition of mass resolving power.
