In a distribution, full width at half maximum (FWHM) is the difference between the two values of the independent variable at which the dependent variable is equal to half of its maximum value. In other words, it is the width of a spectrum curve measured between those points on the y-axis which are half the maximum amplitude. Half width at half maximum (HWHM) is half of the FWHM if the fun… WebPeak shape is determined by calculating the ratio of FWTM over FWHM and the ratio of FWFM over FWHM to check if there is broadening of peak over time. The ideal and acceptable resolution ratio for FWTM/FWHM is 1.82 for Gaussian peak and should be ≤ 1.9 in acceptable practice.
