|def=For a single peak corresponding to singly charged ions at mass ''m'' in a mass spectrum, the [[resolution]] may be expressed as (''[[m/z]]'')/Δ(''m/z''), where Δ(''m/z'') is the width of the peak at a height which is a specified fraction of the maximum peak height. It is recommended that one of three values 50, 5, or 0.5 % should always be used. | |||

It is recommended that one of three values 50%, 5% or 0.5% should always be used. (Note that for an isolated symmetrical peak recorded with a system which is linear in the range between 5% and 10% levels of the peak, the 5% peak width definition is equivalent to the 10% valley definition. A common standard is the definition of resolution based upon being full width of the peak at half its maximum (FWHM) height. | ||
