+ | :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]]. | ||
