Product development in the industrial world can be a long and expensive process. In a competitive market, the window of opportunity for significant revenue can close before a new competitive product could even exit the development cycle. The obvious solution to keeping up in a competitive market is to acquire the product in question, disassemble it, and analyze it. This reverse engineering process can greatly expedite the immediate introduction of competitive products into the marketplace. There are many tools for determining the physical properties of materials that will not be discussed here. The chemical properties can be readily determined by utilizing analytical tools such as gas phase chromatography, atomic absorption spectroscopy and many others. Molecular spectroscopy (infrared and Raman) is among the most powerful tools in the reserve engineering process.
