Are the samples doped, and if so by how much?

The concentration of a chemical in a compound varies across samples, due to uncontrolled factors. A substitute for the compound likewise contains a variable concentration of this chemical. We use Bayesian probability theory to investigate, from measurements of the chemical in samples of the compound, of a manufacturer's version, and the substitute, whether the manufacturer is doping the compound with its substitute --- and if so by how much.
