  1. Resistor Combination tables for (a) 2-inlet fork topology, (b) 3-inlet fork topology, and (c) 3-inlet ladder topology, where the R1 branch runs a 0.34 M solution, and remaining branches run Milli-Q water, which are mixed and manually withdrawn at the output end of each topology. The designed mixing ratio that utilizes as-designed resistance values, Designed χ, and expected mixing ratio from Monte Carlo simulation that takes into account build error, Expected χ, are calculated by using the respective mixing law shown in Table 1. The expected error is two standard deviations from the expected mixing ratio.
