Abstract: The invention relates to a method for marking liquids with at least two mark er substances, characterised in that said marker substances are absorbent in th e spectral range of 600 to 1200 nm and emit fluorescence radiation as a result , and in that the absorption range of at least one marker substance overlaps t he absorption range of at least one other marker substance. The invention also relates to a method for detecting marker substances in liquids which have be en marked according to the inventive method. This method is characterised in th at the sources of radiation used emit radiation in the absorption ranges of the marker substances so that the fluorescence radiation emitted by said marker substances can then be detected, at least one of said radiation sources emitting radiation in the absorption range in which the at least one marker substance overlaps with the at least one other marker substance, and in that the number of sources of radiation used is smaller than or the same as the number of marker substances. The invention also relates to liquids which hav e been marked according to the inventive method.

Abstract: The markers used in a process for marking liquids absorb in the 600-1200 nm spectral region thus emitting fluorescent radiation and have no overlapping absorption regions. One of the markers has a wavelength of more than 850 nm. An Independent claim is also included for a process for detecting markers in liquids which have already been marked comprising using radiation sources which emit in the absorption regions of the markers. The radiation sources are semiconductor laser, semiconductor diode or solid body laser.
