Peak capacity equation

WebEquation (1) indicates that the resolution is the difference between peak retention times divided by the average peak width. In a peak with Gaussian distribution, the peak width is W = 4 σ (where σ is the standard deviation) and the peak FWHM is W0.5h = 2.354σ. Substituting these relationships into equation (1) gives results in equation (2). WebMar 14, 2008 · Peak capacity is the measure of the number of peaks that can fit into an elution time window t1 to t2 with a fixed resolution. One commonly assumes a peak spacing of 4 standard deviations τ (=near baseline resolution), and it has therefore been defined as (1) In the simplest case, the peak width does not change with retention, and Eq.
