ABSTRACT:
A process and an apparatus are useful for identifying articles which are at least partly made from at least one polymer. The process and apparatus use an optical spectrometer and a transport system, whereby the articles to be identified are moved by the transport system past the optical spectrometer, where they are irradiated, response measured and analyzed. An external reference object is also transported, by the transport system, past the optical spectrometer such that it becomes possible to use the measured response for the reference object to identify, with greater accuracy, the articles to be identified.
