Claim:
1. A multilayer paper analytical device for detection of at least two chemical components indicative of a low quality pharmaceutical product or dietary supplement, comprising: one or more assay regions in communication with a non-chemically interfering binder agent disposed adjacent at least one hydrophobic layer; and one or more vessels each having a wall that houses one or more reagents in registry with at least one assay region for which testing for a chemical component is desired; wherein the binding agent and hydrophobic layer provide a fluid path such that rupture of a vessel wall establishes fluid communication between the one or more reagents released by the ruptured vessel wall and a corresponding assay region along the fluid path; wherein each assay region is configured to receive a sample of a suspected a low quality pharmaceutical product or dietary supplement such that, after activation of the device by rupturing of a vessel wall in registry with the assay region, the reagent wets the assaying region for reaction with the sample.
