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 copolymer is prepared by the polymerization of monomers that include an ultraviolet absorbing monomer, and a base-solubility-enhancing monomer. The copolymer is useful for forming a topcoat layer for electron beam and extreme ultraviolet lithographies. Also described are a layered article including the topcoat layer, and an associated method of forming an electronic device.

A process for detecting oil or lubricant contamination in a manufactured product (C), preferably a cigarette (C), the process comprising adding a fluorescent taggant to oils or lubricants contained in processing machinery for said product (C), conveying (131) said product (C) past an infrared detection apparatus (140), irradiating said product (C) with infrared radiation from said detection apparatus (140) as it passes the detection apparatus (140), and detecting infrared radiation emitted from said irradiated product (C). 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.

A device and method for separating non-tobacco related materials from a mass flow. The device includes a feed device to convey the mass flow in a transport direction; a detection device detecting a non-tobacco related material in the mass flow and generating and transmitting a non-tobacco related material detection signal; a rejection device receiving the non-tobacco related material detection signal and removing the non-tobacco related material from the mass flow by deflecting the non-tobacco related material in a rejection direction; a discharge device receiving the mass flow from which the non-tobacco related material has been removed; and a non-tobacco related material receiving device to receive the removed non-tobacco related material. The non-tobacco related material receiving device can include a retaining device in a form of a chute with chute walls delimiting a retaining volume, and at least one deflecting member oriented at a downward angle from the chute walls.
