Predicted depth-averaged, unreacted sample fraction M _R versus the Lagrangian sample residence time t for varied reaction half-lives t _1/2 and fixed sample Q _sa and sheath Q _sh flow rates. The reaction studied involved ascorbic acid H₂Asc and ferricyanide reactants and de­hydro­ascorbic acid Asc and ferrocyanide products. The shaded area near the lines shows the range of possible M _R given variations in sample and sheath species diffusivities of 10%. The second-order decay rate for these simulations was estimated as k = . Data are for initial concentrations of = 40 mM and [H₂Asc]₀ = 200 mM.
