Resolving power - Wikipedia ... Resolving power
Resolution and resolving power, when defined in this way, are consistent with IUPAC recommendations for microscopy, optical spectroscopy. [16] [17] and ion microscopy (SIMS) [18] but not gas chromatography. [13] This definition also appears in some mass spectrometry texts. [19] [20] [21]
Spectral resolution
Visual acuity, or resolving power, is "the ability to distinguish fine detail" and is the property of cone cells. [42] It is often measured in cycles per degree (CPD), which measures an angular resolution, or how much an eye can differentiate one object from another in terms of visual angles. Resolution in CPD can be measured by bar charts of ...

Like in FTICR-MS the Orbitrap resolving power is proportional to the number of harmonic oscillations of the ions; as a result, the resolving power is inversely proportional to the square root of m/z and proportional to acquisition time. For example, the values above would double for m/z 100 and halve for m/z 1600. For the shortest transient of ...
Dawes' limit is a formula to express the maximum resolving power of a microscope or telescope. [1] It is so named after its discoverer, William Rutter Dawes , [2] although it is also credited to Lord Rayleigh. The formula takes different forms depending on the units. This formula agrees with the usual at a wavelength of about 460nm, somewhat ...
