|def=Value of (''[[m/z]]'')/Δ(m/z) measured for two peaks of equal height in a mass spectrum at ''m/z'' and ''m/z'' Δ(''m/z'') that are separated by a valley which at its lowest point is 10 % of the height of either peak. For peaks of similar height separated by a valley, let the height of the valley at its lowest point be 10 % of the lower peak. Then the resolution (10 % valley definition) is (''m/z'')/Δ(''m/z'') and should be given for a number of values of ''m/z''. | |||

Let two peaks of equal height in a [[Mass Spectrum|mass spectrum]] at masses m and m - Δm be separated by a valley which at its lowest point is just 10% of the height of either peak. For similar peaks at a mass exceeding m , let the height of the valley at its lowest point be more (by any amount) than 10% of either peak. Then the resolution (10% valley definition) is m / Δm. The ratio m /Δm should be given for a number of values of m. | Let two peaks of equal height in a [[Mass Spectrum|mass spectrum]] at masses m and m - Δm be separated by a valley which at its lowest point is just 10% of the height of either peak.
