The invention relates to a process and an apparatus for identifying articles which are at least partly made from at least one polymer, using an optical spectrometer and a transport system, said process comprising the steps of: a) moving the articles past the optical spectrometer using the transport system b) irradiating the articles and measuring the response of the irradiated articles using the optical spectrometer, analyzing the response to identify the articles as to the type of polymer wherein the process also comprises the step of c) at least periodically irradiating an external reference object, measuring the response of the irradiated reference object using the optical spectrometer, and using the measured response for the analysis of step b).
Process for identifying articles which are at least partly made from at least one polymer, using an optical spectrometer and a transport system, said process comprising the steps of:
Process according to any one of claims 1-9, characterized in that the reference object is moved past the optical spectrometer using the transport system.
Process according to any one of claims 1-10, characterized in that the reference object is fixed to the transport system and that the fixed reference object is moved past the optical spectrometer, and irradiated.
Process according to any one of claims 1-11, characterized in that the reference object and/or the articles are fixed to transport system and that the fixed reference object and/or the articles are moved past the optical spectrometer, and irradiated.
Process according to any one of claims 1-12, characterized in that the transport system comprises a transport rail, that the reference object and/or articles are fixed to the transport rail and that the fixed reference object and/or the fixed articles are moved past the optical spectrometer, and irradiated.
Process according to any one of claims 1-13, characterized in that the reference object and/or articles are moved past the optical spectrometer, and irradiated in a predetermined position.
Process according to any one of claims 1-18, characterized in that at least part of the articles are at least partly made from polyamide-6 and/or that at least part of the articles are at least partly made from polyamide 6,6.
Process according to any one of claims 1-19, characterized in that the articles are textile articles.
