A process for detecting oil or lubricant contamination in the production of an article by adding a Stokes-shifting taggant to an oil or lubricant of a machine utilized to produce the article or a component thereof, irradiating the articles produced with a first wavelength of radiation, and monitoring the articles for emission of radiation at a second wavelength. The taggant can be in the form of a composition containing a Stokes-shifting taggant, which absorbs radiation at a first wavelength and emits radiation at a second wavelength, different from said first wavelength, dissolved or dispersed in an oil or lubricant.

The invention relates to an apparatus for identifying one or more substances in a materialin particular, wherein the material is present in granulate formcomprising at least one light sourcepreferably in the form of a laserfor irradiating a sample of the material with light of at least one wavelength, a detector for detecting the light re-emitted and/or transmitted by the sample, and an analysis device for the spectroscopic analysis of the detected light, wherein

the analysis device interacts with the detector, and these are embodied in such a way for analyzing the detected light by means of a) UV/VIS spectroscopy and/or b) fluorescence spectroscopy and/or c) Raman spectroscopy and/or d) absorption spectroscopy,
and for creating a first identification result for at least one substance of the sample and, in the case of an ambiguous first identification result, creating a second identification result for the at least one substance on the basis of a e) fluorescence light decay time analysis, FLZA,
wherein the at least one substance is then at least partly identified on the basis of the first identification result or on the basis of the first and second identification results.

A method for detecting mentholated tobacco, comprising irradiating tobacco containing menthol and a fluorescent taggant with radiation and observing the tobacco for fluorescence from the taggant. A system and method for detecting and separating mentholated tobacco from non-mentholated tobacco within a product stream is also provided.

A method of obtaining cullet from a solar module unit is disclosed. The method involves providing a solar module unit in which a detectable tagging material has been applied onto an exposed outer surface of a glass substrate of the solar module unit over one or more electrically conductive contact strips located beneath and visible through the glass substrate. Thereafter, the solar module unit is crushed into assorted module pieces. The assorted module pieces are then sorted by detecting module pieces that include the detectable tagging material and separating the assorted module pieces into a collection of accepted module pieces and a collection of rejected module pieces. The collection of accepted module pieces has module pieces determined not to include the detectable tagging material. Recycled glass is then obtained from the collection of accepted module pieces.
