Webb1 nov. 2024 · Resolution is a measure of the degree of separation between two adjacent signals, detector responses, or, in the case of optical instruments, objects. The general resolution equation is defined as where â s is the spacing between the apex of two signals with respect to their average baseline width, wav = ( w1 + w2 )/2. WebbThe number of steps between the operating lines and the equilibrium line represents the number of theoretical plates (or equilibrium stages) required for the distillation.
