Methods and additives for tagging and subsequently detecting commercial products, including industrial liquids, are disclosed. These methods permit the identification of such tags after very high, say 10<-11> dilutions. The present invention encompasses a method of microtagging a liquid, subsequently detecting that the liquid has been microtagged and identifying the liquid, which comprises (i) adding to the liquid an additive comprising at least one signal means which may be detected after extreme dilution, and a coding means to aid in identification of the liquid; (ii) obtaining a sample of the liquid contaning said additive; (iii) detecting the presence in the liquid sample of said at least one signal means; (iv) and decoding said coding means, thereby detecting that the liquid had been microtagged and identifying the liquid sample. |
