Abstract:
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.
