Resolving power (in mass spectrometry) {{{acronym}}}
mass resolving power

Measure of the ability of a mass spectrometer to provide a specified value of mass resolution.

Note: The procedure by which Δ(m/z) was defined and measured, and the m/z value at which the measurement was made, should be reported.

Resolving power (in mass spectrometry)

The ability to distinguish between ions differing in the quotient mass/charge by a small increment. It may be characterized by giving the peak width, measured in mass units, expressed as a function of mass, for at least two points on the peak, specifically for 50% and for 5% of the maximum peak height.

The ability to distinguish between ions differing in the quotient mass/charge by a small increment. It may be characterized by giving the peak width, measured in mass units, expressed as a function of mass, for at least two points on the peak, specifically at fifty percent and at five percent of the maximum peak height.

Commonly and also acceptably defined in terms of the overlap (or 'valley') between two peaks. Thus for two peaks of equal height, masses and , when there is overlap between the two peaks to a stated percentage of either peak height (10% is recommended), then the resolving power is defined as . The percentage overlap (or 'valley') concerned must always be stated.
