WebResolution and resolving power are terms used in mass spectrometry, various optical spectroscopy techniques such as microscopy, digital image acquisition, and processing tools. A particular (high) mass resolution (e.g. 100,000) is necessary to separate or resolve two peaks that have a certain small mass difference of e.g. 0.01 u.
WebThe resolving power is determined by m / ( m 2 − m 1) at full width half height of a peak. The higher the value obtained the better. This is where I struggle to form a link between the resolution of the mass spectrometer … WebThe term resolving power is often used to describe the ability of a mass spectrometer to resolve adjacent peaks in a mass spectrum and is often used interchangeably with resolution. The separation of peaks for singly charged ions can be expressed as a mass …
