10/09/2008 · The calculation of S/N on EIC is the best if we know the mass of the compound. I would like to calculate the S/N on the mass spectrum to see when a signal can be distinguished from noise also on similar compound but unknown. I found in a recent article that they calculate the S/N for compound A in 3 different ways (but they does'n report how they calculate it):
