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. |

Resolving power (mass spectrometry) http://goldbook.iupac.org/R05321.html 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. mass resolving power http://goldbook.iupac.org/M03730.html 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. Source: PAC, 1978, 50, 65 (Recommendations for symbolism and nomenclature for mass spectroscopy) on page 72 |
