Abstract: A process for real-time classification of materials, the process including: conducting laser induced breakdown spectroscopy on the material (LIBS), wherein at least one second laser pulse is directed to the plume so as to selectively energize only a portion of the plume; measuring optical emissions from the energized portion of the plume; and assessing the elemental composition of the material on the basis of the optical emissions from the excited portion of the plume; wherein the energized portion of the plume is substantially smaller than the entire plume so that the measured optical emissions are relatively independent of the size of the entire plume and hence are relatively independent of the optical absorption and vaporization characteristics of the material, thereby allowing a more accurate assessment of the elemental composition of the material than if the assessment was based on the optical emissions from the entire plume.

Abstract: A method of marking an industrial process material including selectively incorporating a luminescent marker onto and/or into the industrial process material in a trace amount insufficient to be optically detectable in the presence of ambient light but sufficient to be non-destructively optically detectable in and/or on the industrial proce material in situ in the field or on-site. The trace amount of the luminescent marker is used to track, identify authenticate the industrial process material for at least one of material control, inventory control, stock control, logistics control, quality control and pollution control.

Abstract: A method for determining the degree of mixing between components in a mixing process, the method including the steps of: a) mixing at least two components and at least two luminescent materials to form a mixture, wherein the luminescent materials are added to the mixture separately from each other, and wherein each luminescent material has a uniquely detectable luminescence emission wavelength; b) detecting emitted luminescence from a sample of the mixture, wherein the emitted luminescence includes different luminescence intensities at the uniquely detectable luminescence emission wavelengths of the luminescent materials; c) wherein the ratio of luminescence intensities and/or the absolute or relative intensities of luminescence at the uniquely detectable luminescence emission wavelengths is indicative of the degree of mixing between the components.
