METHODS FOR MARKING AND TRACKING AN INDUSTRIAL PROCESS MATERIAL, SYSTEM, AND PORTABLE LUMINESCENCE READER. a method for marking an industrial process material (7) is described which includes selectively incorporating a luminescent marker (1) superficially and / or internally into the industrial process material (7) in a trace quantity insufficient to be optically detectable in the presence of light environment, but sufficient to be optically detectable in a non-destructive way internally and / or superficially in the industrial process material (7) in situ in the field or on site. The trace quantity of the luminescent marker (1) is used to track, identify and authenticate industrial process material (7) for at least one of material control, inventory control, inventory control, logistical control, quality control and control pollution. |
