    Abstract: The present invention relates to a method of marking liquids using at least two markers, wherein said markers absorb in the 600-1200 nm region of the spectrum and reemit fluorescent light and the absorption range of at least one marker overlaps with the absorption range of at least one other marker.The present invention further relates to a method for detecting markers in liquids marked by the method of the invention, which comprises using light sources which emit radiation in the absorption ranges of said markers and detecting the fluorescent light reemitted by said markers, at least one of said light sources emitting radiation in the overlapping absorption range of at least one marker with that of at least one other marker and the number of light sources being less than or equal to the number of markers.The present invention further relates to liquids marked by the method of the invention.

    Abstract: The invention relates to a method for marking liquids with at least two marker substances, characterized in that said marker substances are absorbent in the special 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 the absorption range of at least one other marker substance. The invention also relates to a method for detecting marker substances in liquids which have been marked according to the inventive method. This method is characterized in that the sources of radiation used emit radiation in the adsorption ranges of the marker substances so that the fluorescent 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 in smaller than or the same as the number of marker substances. The invention also relates to liquids which have been marked according to the inventive method. 9 claims
