Mass peak
mass peak

peak (in mass spectrometry)

Localized region of relatively intense detector response in a mass spectrum when ions of a specified m/z are detected. If resolving power is insufficient two or more components of similar m/z may contribute to one unresolved mass peak.

Note 1: Although mass peaks are often associated with particular ions, the terms peak and ion should not be used interchangeably.
Note 2: Care should be used to distinguish mass spectrum peaks from chromatographic peaks in GC-MS and LC-MS.
