Abstract
The invention concerns a method for detection of a marking compound with the formula <IMAGE> said method comprising the following stages: A. a sample that is suspected to contain said marking compound is taken and a) a chemical reaction is produced by bringing the sample into contact with B. a reagent containing i. 20- 60% glycerol; ii. 20-40% water; and iii. 10-50% organic amine; C. the reagent and sample are separated; and D. it is determined if the reagent produces a substantial blue-shifting red color which indicates the presence of the marking compound or b) the marking compound is absorbed and concentrated by B. passing the sample through an activated aluminum oxide chromatography column; C. washing the organic liquid from the column; D. washing the natural dyes of the cited organic liquid from the column; and E. elution with reagent containing components i, ii, and iii as described in step aB, in which an essentially purple-colored zone is formed in the column, which indicates the presence of said marking compound.
