mass resolution
In a mass spectrum, the observed m/z value divided by the smallest difference ?(m/z) for two ions that can be separated: (m/z)/?(m/z).
Note 1: The m/z value at which the measurement was made should be reported.
Note 2: The definition and method of measurement of ?(m/z) should be reported. Commonly this is performed using peak width measured at a specified percentage of peak height.
Note 3: Alternatively ?(m/z) is defined as the separation between two adjacent equal magnitude peaks such that the valley between them is a specified fraction of the peak height, for example as measured by peak matching.
Revised from [5] and from [8, 118, 165, 166].
