In diffusion experiments, concentration profiles are typically measured by using regularly-spaced sampling locations along the diffusion penetration direction. This paper proposes an approach and justification for optimizing the sampling location plan so that uncertainties and errors in the measured diffusion coefficients are minimized. Additional work is presented investigating the role of measurement replications on the uncertainty in the diffusivity. The methods and results presented can help researchers improve diffusion experiment design, and better quantify the quality of their data.
