Detection of a suspect counterfeit part by chromatography

Abstract:

Parts are exposed to liquid chromatography to generate a corresponding chromatogram, wherein the chromatogram is compared to a chromatogram of a genuine part to determine if the tested part is suspect counterfeit. Depending on the selected predetermined target analytes, the generated chromatogram can be used to assess an associated manufacturing process as conforming or non-conforming.
