WebTo determine the full width at half-maximum (FWHM) resolution of a peak in a mass spectrum divide the m/z of the peak by the width of that peak at 50% of its intensity. An value of this number that is greater than 10,000 will give excellent separation of isotopic peaks. For the spectrum above the peak at m/z 824.87 has a FWHM resolution of 47,000.

"There are several ways to define the minimum peak separation ΔM in mass spectrometry, therefore it is important to report the method used to determine mass resolution when reporting its value. The two most widely used are the peak width definition and the valley definition. In the peak width definition, the value of ΔM is the width of the peak measured at a specified fraction of the peak height, for example 0.5%, 5%, 10% or 50%. The latter is called the full width … " - Fwhm chromatography
