It is emphasized that the equations for error amplification described in this paper only apply to yields and recoveries derived solely from a set of three raw assay values for a single species. suggests that rather than estimate the recovery of species i by applying Equation 2 directly to the assays of that species, recovery may be more accurately estimated via a two-step process. First the yield is found via Equation 1 using the species j that gives the highest accuracy (i.e. has the lowest AY,j value), and then the recovery of species i is Table .1: Sample results using the Monte Carlo simula on method with N = 5 simula ons and M = 10 species for a system with yield Y = 0.05.
